In this major, promising technologies such as nanostructures,
non-memory semiconductors, applied optics, and nonlinear complex
systems have been chosen as areas of specialization. Practical
education facilities have been established to provide training
programs at the undergraduate and graduate level. In the field
of nanostructures and non-memory semiconductors, we undertake
research into the processing, modification and characterization
of electronic and optoelectronic materials, and into the design,
fabrication and testing of novel electronic and optoelectronic
devices. Applied optics is becoming an increasingly important
field for all optical telecommunication networks. Four professors
in the field of optics are collaborating with professors specializing
in nonlinear mechanics for a joint theoretical/experimental
approach. Several faculty members specializing in surface
physics, nuclear physics, and optics are performing collaborative
research to solve nonlinear complexities. The Semiconductor
Physics Research group was selected for the Brain Korea 21
Grant by the Ministry of Education. This 7-year research grant
supports monthly salary and travel expenses for graduate students
and postdoctorates. The department has very active and well-funded
research facilities, offering excellent opportunities for
students wishing to proceed to the degrees of Master of Science
or Doctor of Philosophy.
Major facilities established for the major include:
PL system, E-beam evaporator, IR detector characterization
system, spectroscopic ellipsometry system, high temperature
annealing system, wire bonder, tunable diode laser, Ar laser,
reflectance and transmittance measurement system, RF spectrum
analyzer, fusion splicer, He-Cd laser, vacuum evaporator,
workstation.
1) At least 24 course units of graduate level credit in Physics
courses are required for the master's degree and 60 course
units for the doctor's degree (including units completed in
master course).
2) Students have to pass a qualifying examination.
3) Students must fulfill presentation, defense, and document
requirements for the physics thesis committee.
4) A thesis advisor can be any faculty member from the Physics
department

Research Overview
Research in this lab involves the studies of Si or Ge nanostructures
and organic polymers. These studies range from the basic characterization
of these materials to device applications such as light-emitting
diodes and non-volatile memory devices. The nanostructures
are fabricated either by using ion beam sputtering or PECVD
to grow alternate layers of SiO2 and silicon-rich oxide or
by ion-implantation of Si or Ge into host materials such as
fused silica, sapphire, and SiO2. We are also employing several
techniques such as photoluminescence, electroluminescence,
cathodoluminescence, I-V, and C-V for optical and electrical
characterization of these structures. This would enable us
to integrate devices of differing functionalities onto a single
chip.
Ongoing Projects
Fabrication and characterization of silicon-based semiconductor
nanostructures
Improvement in the physical properties of insulating layers
for new functional semiconductor devices
Control of optoelectronic properties in advanced organic materials
and their device applications
Research Overview
Our research at the Semiconductor Photonics Laboratory focuses

Kerr spectroscopy. Main facilities are spectroscopic ellipsometry,
reflectance difference spectroscopy, spectrophotometer, and
