The P-N junction leakage current I R under reverse bias includes the contributions of diffusion current, space charge generation current; band-to-band tunneling current and thermionic emission current. These shunt types are processed-induced, caused by grown-in defects of the material. The process-induced shunts are due to strong …
Photodiodes and other Light Sensors
An ideal diode with reverse bias (i.e. its anode is negative with respect to its cathode) acts as an insulator, but has a small temperature dependent leakage current, largely independent of the reverse bias voltage [7], which doubles with every 10°C increase in the device temperature.There is also a small capacitance in parallel with the diode, which decreases …
