Summary: The investigation of: structural, electrical and optical
properties of: ternary semiconductor compounds of the Ga-In-Se system,
polycrystalline and amorphous silicon, thin films of metal alloys of
transient metals and intercalary thin films, especielly TiO2. The
application of home-invented methods for the samples growth and their
obtaining, as well as the examination of varius influences of the
composition, packing, annealing changes on the growth of some particular
thin films. The project research programme covers the application of very
many experimental techniques: x-ray diffraction, Raman and IR
spectroscopy, DLTS, TSC, XPS, AES, and corresponding numerical
modelling,complementary to the obtained experimental results.
Research goals: The aims of this project are as follows: -Study of
electrical, optical, structural and some other physical properties of
ternary semiconductors, especialy the compounds of the Ga-In-Se systems,
and determination of the optical modes frequencies dependence upon the
compounds compositions. -Research on the formation and degradation of some
high-temperature defects in varius types of polycristalline silicon.
-Investigation of electrical vacuum arc, magnetron discharge
characteristics and formation of metal plasma via high power laser. -Based
on the knowledge of vacuum technologies and discharges in vacuum, our aim
is to build up a magnetron unit, which would provide an opportunity of
getting amorphous silicon, as well as amorphous films of alloy metals
between transient netals with low and high melting point. Special
attention is going to be paid to the structural properties, hydrogen
doping and recrystallization of amorphous silicon, as well as to the
structural, mehanical and electrical properties of transient metal alloys
with tungsten. -Investigation of physical properties of intercalary thin
films and determination of their possible use in terms of electrodes for
some types of galvanic cells. Other information about the project.
