Mechanical properties of pure and doped indium phosphide single crystals

Abstract

The mechanical properties have been studied for the (001) and {111} planes of pure and doped InP single crystals. As was shown the anisotropy of these properties can be successfully investigated by using the sclerometer technique (scratch method) and acoustic emisson method. The influence of doping on microhardness has been revealed to be more pronounced at T/spl sim/600 K than at room temperature.
