Abstract

The single crystal growth of large semi‐insulating GaSe by the vertical Bridgman technique using zone‐refined selenium (Se) and HP gallium (Ga) is described. The grown crystals (up to 10 cm long and 2.5 cm diameter) have been characterized thoroughly by X‐ray diffraction (XRD), energy dispersive analysis by x‐rays (EDAX), optical absorption/transmission, X‐ray photoelectron spectroscopy (XPS), charge carrier electrical property measurements, second harmonic test, and radiation detection measurements.
