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…
Atomically-resolved exciton emission from single defects in MoS
Lysander Huberich, Eve Ammerman, Gu Yu +11
Understanding how atomic defects shape the nanoscale optical properties of two-dimensional (2D) semiconductors is essential for advancing quantum technologies and optoelectronics.…
Photonics in Flatland: Challenges and Opportunities for Nanophotonics with 2D Semiconductors
Ali Azimi, Julien Barrier, Angela Barreda +45
Two-dimensional (2D) semiconductors are emerging as a versatile platform for nanophotonics, offering unprecedented tunability in optical properties through exciton resonance engine…
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…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145

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…
Beam steering with a nonlinear optical phased array antenna
Sebastian Busschaert, Nikolaus Flöry, Sotirios Papadopoulos +3
Transition metal dichalcogenides (TMDCs) exhibit high second harmonic (SH) generation in the visible due to their non-centrosymmetric crystal structure in odd-layered form and dire…
