摘要：
The present paper reports molecular dynamics study of the elastic deformation of zinc-blende GaAs crystal by spherical diamond indenter acting on the (001) plane. The atomic displacements under field of elastic deformation result in generation of characteristic atomic structure with arms located along < 110 > directions. The phase transformation from zinc-blende to rock-salt GaAs structure was recognized in thin volume under indenter.
