Crossover from quantum correlation to hot-carrier transport in scattering-tolerant 2D transistors

Debottam Daw, Houcine Bouzid, Sung-Gyu Lee +6

Quantum correlation and hot-carrier transport represent two fundamentally distinct regimes of electronic conduction, rarely accessible within the same device. Here, we report a sta…
