Competing Channels for Hot-Electron Cooling in Graphene

Competing Channels for Hot-Electron Cooling in Graphene

We report on temperature-dependent photocurrent measurements of high-quality dual-gated monolayer graphene p−n junction devices. A photothermoelectric effect governs the photocurrent response in our devices, allowing us to track the hot-electron temperature and probe hot-electron cooling channels ov...
