ISOTHERMAL CURRENTS IN RED MERCURIC IODIDE SINGLE-CRYSTALS

Isothermal current decay measurements have been performed on red mercu ric iodide single crystals in order to exploit the simplicity of the m ethod in determining the trap depths, trap densities and capture cross -sections of different trapping levels which may be present in the pla telet-shaped single crystals of red mercuric iodide grown by polymer c ontrolled growth (PCG) technique. Some of the important limitations of this method have also been outlined.
