Electron Dose Rate Dependence of Phase Separation Induced by Electronic Excitation in GaSb Nanoparticles

Article Preview

Abstract:

The effect of electron dose rate on phase separation induced by electronic excitation in GaSb nanoparticles has been studied in order to see whether a nonlinear relation between density of excited states introduced and the efficiency of the phase separation is found or not. The phase separation to two phases consisting of an antimony core and a gallium shell proceeds after incubation time with increasing electron dose and does only at the dose rate above a threshold value. It is suggested that such nonlinear behaviors take place as a cooperative phenomenon among electronic-excitation effect, nano-size effect and temperature.
