AMORPHOUS-SEMICONDUCTORS SYNTHESIZED BY HIGH-PRESSURE QUENCHING

Amorphous semiconductors obtained by high pressure quenching (ASHP) are analysed as a new class of materials. These compounds are presented as promising in shedding light on peculiarities of the solid state amorphization process and fruitful in testing some models of an effective medium and scaling and percolation theories. The appearence of many component systems under high pressure treatment, amorphization induced superconductivity, metastable phases stability regions and doping conditions are studied using a wide set of experimental methods which allow us to establish the set of phase transitions and its interconnections for ASHP under variation of different parameters.
