Induced defects in sintered lead telluride

The effect of the pressing and sintering processes on some typical properties (carrier mobility and Hall effect) is analysed. In order to do this, samples obtained from powdered and pressed materials were submitted to a slow sintering process. During and after the thermal treatment, the samples were examined using both transport measurements and a scanning electron microscope in order to evaluate the sintering process. Thus some of the defects which influence electrical property variations have been seen.
