Graphene-based detector for W-band and terahertz radiations

A system for detecting W-band and terahertz radiations, the system comprising:

• a graphene-Si Schottky diode associated with a source electrode and a drain electrode;
• a power source coupled with the source electrode and the drain electrode and configured to apply a reference voltage between the source electrode and the drain electrode;
• a measurement instrument configured to measure a generated current between the source electrode and the drain electrode;
• and
• a processing unit configured to compare the measured generated current with a reference current, and to detect the W-band and terahertz radiations based on the comparison.
