WebThe circuit symbol of tunnel diode is shown in the below figure. In tunnel diode, the p-type semiconductor act as an anode and the n-type semiconductor act as a cathode. We know that a anode is a positively … WebA typical equivalent circuit model for p-i-n PD consists of a current source with the single-pole frequency response representing the photogenerated carrier transport [12, 13] . Previously, we ... The tunnel diode is a semiconductor p-n junction diode. It differs from the usual rectifier-type diodes in that the semiconductor materials are very heavily doped, perhaps as much as 1000 times more than in ordinary diodes. This heavy doping results in a junction which has a depletion layer that (with a typical … See more Unless energy is imparted to electrons from some external source, the energy possessed by the electrons on the n side of the junction is … See more Although Tunnel Diode Equivalent Circuit could be made from any semiconductor material, initially germanium and then gallium antimonide and gallium arsenide have been preferred in practice.
