Phonon assisted absorption in Transition Metal Dichalcogenide heterostructures
Yifan Liu, Robert Dawson, Nathaniel Gabor +1
The coupling of atomic vibrations to electronic excitations - traditionally understood to be a source of energy loss in semiconductors - has recently been explored in photosyntheti…
Ultrafast Charge-Doping via Photo-Thermionic Injection in van der Waals Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Van der Waals (vdW) heterostructures of two-dimensional (2D) materials have become a rich playground for the exploration of correlated quantum phases, and recent studies have begun…
Photoinduced Metal-to-Insulator Transitions in 2D Moiré Devices
Yiliu Li, Esteban Rojas-Gatjens, Yinjie Guo +10
Photoexcitation has been utilized to control quantum matter and to uncover metastable phases far from equilibrium. Among demonstrations to date, the most common is the photo-induce…
Dirac excited state quenching in graphene
Jacky C. Wan, Trevor B. Arp, Nathaniel M. Gabor
Hot, dense phases of Dirac fermions - predicted to resemble relativistic plasma - are uniquely accessible through photoexcitation of pristine, charge neutral graphene. We demonstra…
