Metal–Semiconductor–Metal Photodetectors

Source: MDPI Understanding Metal–Semiconductor–Metal Photodetectors Understanding Metal–Semiconductor–Metal Photodetectors Introduction to MSM Photodetectors Metal–Semiconductor–Metal (MSM) photodetectors are a type of photodetector device that employs two Schottky contacts, or metallic electrodes, on a semiconductor material. Unlike traditional p–n junction photodiodes, MSM photodetectors use a pair of Schottky junctions. When operational, an electric voltage is applied to these […]

Source: HZDR Informative Blog Post on Photocathodes Understanding Photocathodes What is a Photocathode? A photocathode is an electrode made from a material that emits electrons when exposed to light, a phenomenon known as the external photoelectric effect. These emitted electrons can be collected as a photocurrent by an anode held at a positive potential. Applications

Vacuum Noise

Vacuum Noise

Source: YouTube Understanding Vacuum Noise in Quantum Optics Understanding Vacuum Noise in Quantum Optics Vacuum noise is a fundamental concept in quantum optics, arising from the inherent fluctuations of the electric field in a vacuum state. Even when there is no photon present, these zero-point fluctuations exist, contributing to what is known as vacuum noise.
