National property
The SRC «Carat» possesses an unique
laboratory-production complex (further «Complex») for growing both bulk and
thin film compounds of complex oxides and comprehensive investigation of their
physico-chemical properties. It is included by Ukrainian Government (Order of
the Cabinet of Ministers of Ukraine No. 73-p of February 11, 2004) into list of
scientific entities that is a National Property of Ukraine.
The Complex basis is technological equipment for
growth both bulk single crystals and single crystal films that has been
designed and manufactured by leading French companies «Physitherm» and «LAS»
under technical requirements of the SRC «Carat». It consists of:
- Eight automatized growth machines of the «Galaxie
Mark III» type (Physitherm), that is intended for growing large-sized single
crystals of high melting point complex oxide compounds by Czochralski method. The
machines give possibility to grow high quality single crystals in controlled
gas environment with melting point till 2000 С and mass till
- Integrated functional module made by «LAS» Company
is intended for fabrication of single crystal films of complex oxide compounds
(mainly rare earth garnets) by liquid phase epitaxy (LPE) method. The facility
provides a fabrication of defect-free epitaxial films on substrates with
diameter till
All technological processes on the above equipment
perform in automated run mode under computer control.
The main idea line of the Complex foundation is
comprehensive investigations, elaboration of physico-chemical fundamentals for
crystallization of the complex oxide compounds and development of technological
processes for fabrication of functional single crystal materials with set-up
parameters on the base of obtained knowledge.
The Complex is provides with needed independent
systems for supplying energy carriers and technological microclimate, i.e. it
locates in class «100» clean room.
The Complex equipment is unique and being at level of
the best world samples. It has not any analogs in
Availability of the Complex provides to Ukrainian
scientists and technologists a possibility for carrying out both basic
investigations and applied developments on creation of technological processes
for fabrication of new single crystal high-tech materials, which is widely
using in quantum electronics, optoelectronics, acousto- and electrooptics,
integrated optics, photonics, magnetoelectronics, spintronics, functional
sensorics, bioelectronics, etc.
