Abstract :
We have investigated the effects of alloy composition (y) on gain of a Ge1-ySny heterostructure avalanche photodiodes (APDs). The band-offsets become a function of alloy composition and affect the carrier confinement at heterointerfaces. The photocurrent is computed using the composition dependent parameters and, hence, the effect of alloy composition on gain of the APDs have been investigated.
