主 题:Te doped GaSb annealing Hall effect measurement photoluminescence spectroscopy IR optical transmission
摘 要:GaSb is the most suitable substrate in the epitaxial growth of mixed semiconductors of GaSb *** this work,Te-doped GaSb bulk crystals with different doping concentration have been annealed at 550℃ for100 h in ambient *** annealed samples have been studied by Hall effect measurement,infrared(IR)optical transmission,Glow discharge mass spectroscopy(GDMS) and photoluminescence(PL) *** annealing,Te-doped GaSb samples exhibit a decrease of carrier concentration and increase of mobility,along with an improvement of below gap IR *** acceptor related electrical compensation analysis suggests a formation of donor defect with deeper energy *** mechanism of the variation of the defect and its influence on the material properties are discussed.
