Graphene-insulator-superconductor junctions are demonstrated as thermoelectric bolometers, capable of detecting power levels around 10−16 W with a response time of approximately 200 ns. This passive device directly converts input power to voltage, showing potential for applications like large-array cosmological experiments.

Researchers have developed a graphene-based detector capable of sensing a faint $10^{-16}$ watts of power, a threshold comparable to detecting just a few photons at certain frequencies. The device, a graphene-insulator-superconductor junction acting as a thermoelectric bolometer, achieves this sensitivity without requiring an external power source, directly converting incoming power into a measurable voltage. Numerical simulations reveal a response time of approximately 200 nanoseconds, allowing…
