Abstract
ZnSe single crystals were grown from n-type microcrystalline boules by :I solid phase recrystallization (SPR) method. During. SPP,. twinned regions appear with different electronic recombination properties. The recrystallizations were performed under different atmospheres, Ar or Se? and pressures to investigate the influence of growth conditions oil these structural features. Recombination properties were studied by means of cathodoluminescense (CL) and remote-electron beam induced current (REBIC). Wavelength dispersive X-ray (WDX) mappings were also performed to analyze possible differences in stoichiometry related to the presence of extended defects.
