Research
Accomplishments
(Ref. Numbers are referred to the publication list following this section.)
A. Growth front morphology study (with
G.-C. Wang)
The group has published a series of seminal papers on the
theoretical predictions and the measurements of morphological evolution during film growth and etching. They have
developed a class of theoretical models and backed by experimental
verification, based on a re-emission mechanism to describe commonly occurred growth/etch front roughening phenomena induced by deposition or etching noise during
processing [Phys. Rev. Lett. 82, 4882 (1999); Phys. Rev. B. 61, 3012 (2000);
Phys. Rev. B. 62, 2118 (2000)]. This generic class of theories can be applied
to many diverse processes such as vacuum evaporation, chemical vapor
deposition, sputter deposition, and plasma etching and ion beam etching. The
team also developed a novel volume
diffusion mechanism to describe the morphology evolution
during the growth of their polymeric films by physical vapor
deposition-polymerization [(Phys. Rev. Lett. 85, 3229 (2000)].
More recent interest focuses on a particularly class of deposition technique
called the oblique angle deposition. This technique allows one to produce 3D
nanostructures that cannot be obtained by other lithographic techniques. Many
electrical, mechanical, and thermal properties of these nanostructures are
actively being studied.
B. Diffraction Theory
Development
Diffraction from stepped surfaces (1979-1981): As a
Research Associate in Wisconsin-Madison (under Professor Max Lagally):
Developed a theory of diffraction from
surfaces with a random distribution
of steps (Ref. 17). In particular the use of the "boundary structure
factor" to quantify the diffraction beam shape is still frequently used by
researchers to quantify surface step distribution.
Intensity oscillations
(1982-present): Proposed a simple explanation of the well-known
intensity oscillation in molecular beam epitaxy using a two-dimensional,
two-level lattice gas model (Ref. 25) (1984). Developed a more sophisticated
one-dimensional theory (also, independently by P. Cohen's group at Minnesota)
of diffraction from surfaces with
two-level, randomly distributed
steps, the so-called (1x1) surface islands, to quantify the intensity
oscillation for layer-by-layer epitaxial growth systems (Refs. 26, 30)
(1984-1985). A more realistic, two-dimensional theory was constructed in 1992
for two-level, randomly distributed
(1x1) islands (Ref. 146). A quantitative theory to describe the decaying of the
intensity oscillation as a result of roughening of the growth front was also
constructed in 1995 (Ref. 186).
Diffraction from growth/etch front kinetic roughening (1992):
A diffraction theory with an analytical form was developed for a
time-dependent, far-from-equilibrium
growth/etch front that is undergoing a kinetic roughening transition which
obeys a dynamic scaling behavior (Ref. 160). The existence of a
"time-invariant structure factor" was predicted (Ref. 148). This laid
the foundation for experimental diffraction studies of this exciting and new
research area.
Diffraction from unstable growth fronts (1997): An
analytical solution was obtained for
the diffraction from a growth front
that is not stable and that exhibits a "mounds" structure as a result
of a step diffusion barrier (Schwoebel barrier) recently observed in molecular
beam epitaxy (Ref. 217). Many of the predictions have not been observed in
experiments yet. This theory, together with the results obtained for kinetic
roughening will allow experimentalists to probe and gain insights into the
dynamics of film growth, a subject of great interest both from the fundamental and practical point of views.
C. Experimental Surface and
Overlayer Ordering (Collaboration With Professor G.-C. Wang)
Clean surface and overlayer
ordering (in the 80's): a) physical realization of a two-dimensional
Ising-like critical phenomenon in an
overlayer (O/W(112)) (Ref. 38); b) measurement of an infinite-order, surface
roughening transition in a flat metal surface (Pb(110)) (Ref. 95), including the observation of a critical line and a
pre-roughening phenomenon in this
transition (Ref. 146) ; and c) the observation of a vacancy induced surface
disordering in Pb(100) before surface melting (Ref. 132).
Overlayer dynamic ordering
(in the early 80s to present): a) physical realization of the Lifshitz-Allen-Cahn curvature driven growth
mechanism during the two-dimensional domain
growth of an overlayer (Ref. 22) (1983); b) physical realization of the random field Ising effect in the two-dimensional domain growth of an overlayer (Ref. 68) (1988); c)
experimental study of growth front dynamics far from
equilibrium: the observation of a time-invariant structure factor (predicted
earlier) from an epitaxial growth
front (Ref. 150) (1992); and d) dynamic scaling of a different kind (unstable
growth) using the high-resolution
low-energy electron diffraction technique was also discovered: epitaxial growth
of Si/Si (Ref. 173) (1994), sputtering of Si (Ref. 172) (1994), amorphous
growth of Si/Si (Ref. 194) (1996).
Light
scattering (1995-present): A major advancement has been made in the
light scattering techniques for surface roughness and dynamic growth front
study: an improvement of four orders of magnitude in temporal resolution (Ref. 195) and two orders of magnitude in
spatial resolution (Ref. 178). The
time resolution has been improved from a few minutes/profile measurement to a few milliseconds/profile
time scale and at the same time the dynamic range of interface width has been
improved two orders of magnitude. This development represents a major
breakthrough in using light scattering technique for real-time growth/etch
front study (Ref. 196) (1996).
D. Self-Ion Assisted
Deposition Techniques
Ionized cluster beam deposition (early to mid 80's):
To provide a fundamental understanding of on the mechanism of metal and
semiconductor cluster formation in
ionized cluster bean deposition
(Ref. 35). Critical size was determined and the long standing controversy on
the metal and semiconductor cluster
formation in ionized cluster beam
deposition was resolved (Ref. 72). A novel multistate condensation strategy was
developed to study in detail the dynamics of cluster
formation in a supersonic expansion from
a crucible and cluster size
distribution was determined (Ref. 47).
Partially ionized beam (PIB)
deposition (mid 80's to present): Invention and creative
design of a class self-ion assisted deposition sources for self-ion assisted
deposition techniques, called the partially ionized beam deposition (Ref. 66)
(1988), to grow very unusual metal and insulator thin films and interfaces at
low substrate temperatures. Using this technique, an ideal single crystal Al
film which was incommensurate to the
substrate was deposited on a Si(111) surface under a conventional vacuum
condition at room temperature (Ref.
84). Other interesting examples using the PIB deposition techniques are: 1) room temperature epitaxy of metal on GaAs substrates
in a conventional vacuum condition (Ref. 201); 2) room
temperature deposition of bulk-like resistivity metal films (Ref. 98); 3)
growth of perfectly oriented polycrystalline metal films with unusually tight
texture on amorphous substrate (Ref. 86); 4) order of magnitude improvement of
electromagnetic lifetime of PIB
deposited films (Ref. 88); 5) dramatic improvement of adhesion of metal films
on polymer substrates (Ref. 197); 6) the ability to fill high aspect ratio
vias/trenches with metal (Ref. 62); and 7) room
temperature coating of dense and transparent oxides and ceramic films with
extremely low dc leakage current (Ref. 130).
PIB mechanism: A
fundamental mechanism for PIB film growth has been proposed to explain the
observed film growth at low substrate temperature. A model involving the
generation of a high temperature, high mobility layer near the region of ion
impact at the growth front has been successfully developed to account much of
the observed unusual growth behavior of the PIB deposition (Ref. 105, and
theses by P. Bai and B. Gittleman).
E. Vapor Deposition of Novel
Polymeric Films
Development of novel vapor
deposition techniques for polymers and polymer composites
(1990-present): Vapor deposition techniqueswere developed to deposit
polymeric films with very low dielectric constant and films with very high
electro-optics coefficient. Examples are the deposition of Parylene-F films
using a monomer liquid, C 8
F10 (Ref. 209); and the deposition of novel polynathalene films
(with Professor J. Moore) using a new precursor (Ref. 189). In contrast to the
conventional spin-on polymers, these films are polymerized at very low
substrate temperatures and are coated in a vacuum condition where no moisture
is trapped. Co-polymerized thin films (Ref. 199) and polymer-chromophore composite
films (Ref. 182) with very high electro-optic coefficient were created using
the vapor deposition techniques.
