THERMAL
PHYSICS LABORATORY
The
main activity of the group is the preparation
of new materials and their characterization.
The rare-earth silicates R2 SiO5 and R2Si2O7(R=Tm,
Er, Ho, Dy, Tb) have been prepared either
in the poly or single crystals. The polycrystals
have been prepared by the solid state reaction
and the single crystals by the flux method.
These materials have been characterized
by the x-ray diffraction and thermal transport
properties. Single crystals of these materials
are available for physical measurements.
After
the discovery of high-Tc superconductivity,
the group has been involved in the preparation
of `123' and Bi-based materials. The single
crystals of Bi-based superconductors have
been prepared by the flux method, various
physical measurements like x-ray diffraction,
dc electrical resistivity, low field AC
susceptibility and thermal conductivity
have been made. Most of the equipment with
on-line computers, mentioned above are available
in the research laboratory. The X-ray Diffractometer
is again within the reach of the research
group. Recently, the research activity has
been extended to the growth of thin films
of semiconducting / superconducting materials.
Again the physical properties of these films
are also studied.
