Why does cooling benefit performance of a HgCdTe device? Given band gap of HgCdTe = 0.1eV. (Calculate it) Briefly discuss how a photoconductive sensor works with a diagram.
Homework Answers
Because
thermal energy of electron at room temperature is equal to 0.026 eV
which is comparable to the band gap energy.
so is the temperature increases of decreases it will greatly affect the band gap.

1. Data management, device management and network management of IoT is crucial to data integrity and transmission. T F 2. An IoT application is a set of wireless devices that act together to perform some sensing and control function. Most applications also provide a user interface, such as a mobile app or cloud-based service. In general, each application is deployed independently of any other applications that may be operating in the area and forms its own separate, cryptographically isolated network....
