What are the characteristic of photo diode?
A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.
Which diode does not use negative resistance in its operation?
Backward diode
How do a schottky diode and ordinary pn junction differ in their operation?
The schottky diode is based on a metal-semiconductor junction, called a schottky barrier, that results in lower forward voltage and vastly decreased switching time. While an ordinary silicon diode has a forward voltage around 0.7 volts, with a germanium diode around 0.3 volts, the schottky can be as low as 0.15 volts. The switching time can be in the tens of picoseconds range, compared to hundreds of nanoseconds. The downside is limited reverse voltage rating and poor reverse voltage leakage, which increases with temperature, causing potential thermal runaway.
What is the Principle Of Gunn Diode?
The Gunn diode operates based on the principle of negative differential resistance, which occurs in certain semiconductor materials like gallium arsenide. When a voltage is applied, the diode can switch between two energy bands, leading to a reduction in current despite increasing voltage. This characteristic enables the Gunn diode to generate microwave frequencies and is widely used in oscillators and amplifiers. Its ability to produce high-frequency signals makes it valuable in telecommunications and radar systems.
Is diode characteristic symmetrical?
Absolutely not. An ideal diode's characteristic would be perfect conduction in the forward direction and perfect insulation (no conduction) in the reverse direction. Silicon diodes come respectably close.

What is the difference between a Shockley diode and a Shottky diode?
A Shockley diode is a primitive diode identical to a thyristor with it's gate left disconnected. A Schottky diode is similar to a normal avalanche diode except that it's forward voltage is quite low, and it's switching speed is very high.
