The Schottky-barrier diode has: Correct Answer no PN junction

Schottky Diode:

A Schottky Diode is a metal-semiconductor diode with a low forward voltage drop and a very fast switching speed.

  • A Schottky diode is formed between metal and semiconductor (n-type), thus there is no p-n junction in the Schottky diode.
  • Schottky diodes have less recovery time compare to normal diodes and hence provide fast switching speeds.
  • Schottky diodes are used in high-frequency applications.

 

Schottky diode I-V characteristic-

The I-V characteristic is generally that shown below. In the forward direction the current rises exponentially, having a knee or turn on voltage of around 0.2 V. In the reverse direction, there is a greater level of reverse current than that experienced using a more conventional PN junction diode.

Select the option that is true regarding the following two statements labeled Assertion (A) and Reason (R). Assertion (A): Whenever we measure an electrical signal, there are chances of over current which leads to overheating of the meter. In such cases, the meter can be protected by using a semiconductor diode of suitable rating. Reason (R): As soon as the diode is short-circuited, the meter current is diverted through the diode. As a result, the meter is being protected from excess heating.
Assertion (A): A p-n junction diode with low junction depth can be used as a solar cell when illuminated by suitable light (wavelength) at the top thin layer above the junction. Reason (R): A p-n junction diode under no condition can be used as a solar cell. It can be used only as a light-emitting diode for optoelectronic applications.
