摘要: A window structure InGaAsP avalanche photodiode (a.p.d.) has been fabricated by using liquid-phase epitaxy on (111B) InP. Multiplication characteristics show that the impact ionisation rate for electrons is larger than holes (?>s). The ratio ?/s was estimated to be 3?4. low-noise a.p.d. will realised a with electron-initiated multiplication.
