Researchers have designed lateral germanium p-i-n photodetectors with distributed Bragg reflector (DBR) structures, which enhance performance metrics like responsivity and detectivity while ...

Dark Current: The small amount of current that flows through a photodetector even in the absence of light, which can affect the device's sensitivity. Responsivity: The measure of a photodetector's ...

In this study, a multilayer MoS 2 field-effect transistor (FET) photodetector was prepared ... MoS 2 during the pre-transfer process, high responsivity and specific detectivity were achieved ...

Liquid-based photodetector leverages water molecules for quantum dot enhancement, offering high sensitivity and wavelength-specific customization for optical and medical applications.
