The enhanced optical property of chemical passivated n type GaSb

In the paper, Te-doped n type GaSb was passivated by (NH
4
)
2
S, the optical and surface properties of passivated GaSb were investigated by PL and AFM. After passivation treatment, the luminescence intensity of GaSb was enhanced. The passivation time would also affect luminescence intensity and the surface smooth of GaSb.
