WebFeb 24, 2015 · level drops completely across the APD. 2. When an avalanche occurs, high current is drawn, though limited by the resistor. As the current drawn by the APD increases, the voltage drop across the resistor increases. This, in turn, decreases the voltage across the APD, eventually decreasing it below breakdown and the avalanche ceases. 3. WebHgCdTe electron-initiated avalanche photodiodes is presented. The first HgCdTe LMPC 2x8 format array fabricated in 2011 with 64 µm pitch was a remarkable success in terms of …

The planar APDs have a low background doping of 2 × 10 14 c m − 3 and large depletion widths approaching 8 μm. The thick depletion width enabled a gain of 330 to be achieved at −26 V at 200 K without inducing a significant tunneling current.
