A Study of the Avalanche Multiplication and Excess Noise in Al x In1- x AsγSb1‑ γ Avalanche Photodiodes Lattice-Matched to GaSb

{{output}}
High-sensitivity linear-mode avalanche photodiodes (APDs) that operate beyond 1.65 μm and up to 2 μm require a narrow bandgap that also gives rise to high dark currents, especially when subject to the large electric fields necessary for avalanche multiplicat... ...
