A tunnel diode is usually constructed with Gallium. The compounds of Gallium such as Gallium Arsenide and Gallium Antimonide are considered appropriate for tunnel diode. The reason behind this is the ratio of the peak value of forward current and the value of valley current. See more The charge carriers can easily cross the junction as the width of the depletion layer has reduced up to a large extent. Thus, charge carriers do not need any kinetic energy to move … See more When the P-type semiconductor is heavily doped, then the concentration of holes is higher. On the contrary, the concentration of electrons is lower. While in heavily doped N-type semiconductor, the concentration of … See more The volt-ampere characteristics of Tunnel diode is different from the conventional P-N junction. This is due to negative resistance section in the case of the tunnel diode. When forward … See more WebIn this lesson, we describe the characteristics of the tunnel diode. This device finds use at high frequencies. Applications explored are the relaxation oscillator and the harmonic …
