Metal-semiconductor Metal Photodiodes
It is also called Schottky-barrier photodiodes. These photodiodes are made from metal and semiconductor heterojunction. A thin semi-transparent metal film is used in place of the p-type or n-type layer in the p-n junction photodiode. The thin film is mostly made of a metal-semiconductor alloy that acts like a metal. The Schottky barrier photodiodes have fast response and large operating bandwidth.
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. In this Article, We will be going through Photodetector, We will start our Article with What is Photodetector?, Then we will go through its brief Working, then we will go through its properties and go through all the types, At last, we will conclude our Article with Advantages, Disadvantages and Some FAQs.
