Photodetector
What is Photosensor?
A photosensor or photodetector is a type of optoelectronic device that is used to convert light energy or radiation into electric signals.
Which is the best material used for making photodetector?
Graphene is the best material for making photodiodes. It is an allotrope of carbon.
What are the steps involved in the working of a photodetector?
A photodetector operates in three steps-
- Absorption of photons.
- Transportation of newly generated charge carriers.
- Production of photocurrent from the charged carriers.
What do you mean by dark current?
A photocurrent that flows even in the absence of incident light is termed a dark current.
Why Schottky-barrier photodiode is useful other than p-n or p-i-n photodiodes?
The response time and operating speed of the Schottky photodiode is faster than the other photodiodes.
Photodetector
A photo is nothing but light. A detector is nothing but a device that detects something. Therefore, we can directly conclude that a photodetector can be defined as a device that is used to detect light radiations by absorption.
