Sub-nm range momentum-dependent exciton transfer from a 2D semiconductor to graphene
Aditi Raman Moghe, Delphine Lagarde, Sotirios Papadopoulos +11
Heterostructures made from atomically thin semiconductors (here MoSe) and graphene are uniquely poised to investigate photoinduced charge and energy transfer in the 2D limit. H…
All-electrical near-field injection of excitons in a van der Waals antiferromagnet
Jonas D. Ziegler, Sotirios Papadopoulos, Antti J. Moilanen +8
Van der Waals materials have become a promising building block for future electronics and photonics. The two-dimensional magnet CrSBr came into the spotlight of solid state researc…
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…
