Exciton-assisted electron tunneling in van der Waals heterostructures
Lujun Wang, Sotirios Papadopoulos, Fadil Iyikanat +8
The control of elastic and inelastic electron tunneling relies on materials with well defined interfaces. Van der Waals materials made of two-dimensional constituents form an ideal…
Overbias photon emission from light-emitting devices based on monolayer transition metal dichalcogenides
Shengyu Shan, Jing Huang, Sotirios Papadopoulos +5
Tunneling light-emitting devices (LEDs) based on transition metal dichalcogenides (TMDs) and other 2D materials are a new platform for on-chip optoelectronic integration. Some of t…
Energy transfer from tunneling electrons to excitons
Sotirios Papadopoulos, Lujun Wang, Takashi Taniguchi +2
Excitons in optoelectronic devices have been generated through optical excitation, external carrier injection, or employing pre-existing charges. Here, we reveal a new way to elect…
Global strain-induced scalar potential in graphene devices
Lujun Wang, Andreas Baumgartner, Péter Makk +6
By mechanically distorting a crystal lattice it is possible to engineer the electronic and optical properties of a material. In graphene, one of the major effects of such a distort…
Compact SQUID realized in a double layer graphene heterostructure
David I. Indolese, Paritosh Karnatak, Artem Kononov +7
Two-dimensional systems that host one-dimensional helical states are exciting from the perspective of scalable topological quantum computation when coupled with a superconductor. G…
Out-of-plane corrugations in graphene based van der Waals heterostructures
Simon Zihlmann, Péter Makk, Mirko K. Rehmann +7
Two dimensional materials are usually envisioned as flat, truly 2D layers. However out-of-plane corrugations are inevitably present in these materials. In this manuscript, we show…
