Towards sensitive terahertz detection based on graphene quantum dot bolometer (Conference Presentation)

Light absorption in graphene causes a significant change in electron temperature due to the low electronic heat capacity and weak electron-phonon coupling. This property makes graphene a beautiful material for hot-electron bolometers (HEB). However, along with the above advantages, a major challenge remains that, with weak electron-phonon scattering, the resistance is only weakly temperature dependent for pristine graphene. It is thus...
