Abstract

Borkovskaya L.V. Role of macrodefects in electronic and ionic processes
in crystals and epitaxial layers of II-VI compound.-Manuscript.

Thesis for a candidate degree in physics and mathematics by speciality
01.04.07 — solid state physics. — Institute of Semiconductor Physics of
National Academy of Sciences of Ukraine, Kyiv, 1999.

It is shown that dislocation decoration by points defects in CdS
crystals leads to extension of fundamental band edge in long wavelength
region due to state density tail formation in near dislocation regions.
These effect is established to manifest itself in transformation of
edge photoluminescence spectrum shape and degradation processes in
electron beam pumped lasers. Effect of athermal gathering of donors on
dislocations under pulse ultrasound is revealed. It is shown that
photostimulated formation of shallow donors in CdS crystal volume is
caused by dissociation of clusters which consist of cadmium atoms.
Photoluminescence lines connected with macrodefects are identified in
ZnTe/GaAs and ZnSe/GaAs epitaxial layers. It is shown that near surface
region of these layers contain increased concentration of linear and
point defects.

Key words: dislocation, decoration, laser.
