Photoconductive cells are light-sensitive resistors in which resistance decreases with an increase in light intensity when illuminated. These devices consist of a thin single-crystal or ...

There are several methods for generating terahertz radiation: Photoconductive Antennas: Among all the proposed THz sources, the THz-PCA (photoconductive antenna) is the most promising one due to its ...

Detection of light by photoconductivity differs from the detection of light by a photodiode in one significant way. The photoconductive detector can be designed to have built-in gain. That is, the ...

Researchers at the National University of Singapore have found that terahertz light causes unique electron flow in doped graphene.

vidicons do suffer from latency due to the time required for the charge to make its way through the photoconductive layer. It makes up for this by having better image quality in general and no ...

Here, THz pulses are produced by using ultrashort laser pulses to excite a specially fabricated photoconductive switch. The switch is connected to an antenna that radiates the THz pulse to the ...

Cameras are a funny rabbit hole to fall down as a hacker, because we have well over a century of items to pick and choose ...
