Main research directions
We are studying size effects
in phase transitions, structure and surface phenomena in
condensed films of various materials and alloys. Main attention
is devoted to the following directions:
highlighting the role
of size effect among others in such phenomena as:
-
melting and crystallization of
island and continuous films;
-
melting and supercooling upon crystallization
in two-component
films;
-
polymorphous transitions in thin films;
-
wetting phenomena in island films;
-
binary phase diagrams of different types;
-
peculiarities of structure of condensed films,
mainly investigation of lattice
parameter dilatation;
-
distribution of islands over size depending
on their formation conditions.
utilization of thin
films for obtaining new information about fundamental
properties of condensed
matter:
-
surface energy,
their size and temperature dependencies;
-
ultimate supercooling upon
homogeneous crystallization;
-
binary phase diagrams.
Objects: thin metal films and alloys (0.1 - 1000 nm) prepared
by PVD methods on various substrates.
Methods: electron microscopy
(TEM, SEM, STM), HEED, EDX, X-RAY diffraction, new methods developed
in the group.
