Band gap formation in commensurate twisted bilayer graphene/hBN moir\'e lattices

Autor: Rothstein, Alexander, Schattauer, Christoph, Dolleman, Robin J., Trellenkamp, Stefan, Lentz, Florian, Watanabe, Kenji, Taniguchi, Takashi, Kennes, Dante M., Beschoten, Bernd, Stampfer, Christoph, Libisch, Florian

Publikováno v: Phys. Rev. B 109, 155139 (2024)

We report on the investigation of periodic superstructures in twisted bilayer graphene (tBLG) van-der-Waals heterostructures, where one of the graphene layers is aligned to hexagonal boron nitride (hBN). Our theoretical simulations reveal that if the

Strain fingerprinting of exciton valley character

Autor: Kumar, Abhijeet, Yagodkin, Denis, Rosati, Roberto, Bock, Douglas J, Schattauer, Christoph, Tobisch, Sarah, Hagel, Joakim, Höfer, Bianca, Kirchhof, Jan N, López, Pablo Hernández, Burfeindt, Kenneth, Heeg, Sebastian, Gahl, Cornelius, Libisch, Florian, Malic, Ermin, Bolotin, Kirill I

Momentum-indirect excitons composed of electrons and holes in different valleys define optoelectronic properties of many semiconductors, but are challenging to detect due to their weak coupling to light. The identification of an excitons' valley char

Strain fingerprinting of exciton valley character in 2D semiconductors

Autor: Abhijeet M. Kumar, Denis Yagodkin, Roberto Rosati, Douglas J. Bock, Christoph Schattauer, Sarah Tobisch, Joakim Hagel, Bianca Höfer, Jan N. Kirchhof, Pablo Hernández López, Kenneth Burfeindt, Sebastian Heeg, Cornelius Gahl, Florian Libisch, Ermin Malic, Kirill I. Bolotin

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-8 (2024)

Abstract Intervalley excitons with electron and hole wavefunctions residing in different valleys determine the long-range transport and dynamics observed in many semiconductors. However, these excitons with vanishing oscillator strength do not direct

Mapping quantum Hall edge states in graphene by scanning tunneling microscopy

Autor: Johnsen, T., Schattauer, C., Samaddar, S., Weston, A., Hamer, M., Watanabe, K., Taniguchi, T., Gorbachev, R., Libisch, F., Morgenstern, M.

Publikováno v: Phys. Rev. B 107, 115426 (2023) (editors suggestion)

Quantum Hall edge states are the paradigmatic example of the bulk-boundary correspondence. They are prone to intricate reconstructions calling for their detailed investigation at high spatial resolution. Here, we map quantum Hall edge states of monol

Strain control of hybridization between dark and localized excitons in a 2D semiconductor

Autor: López, Pablo Hernández, Heeg, Sebastian, Schattauer, Christoph, Kovalchuk, Sviatoslav, Kumar, Abhijeet, Bock, Douglas J., Kirchhof, Jan N., Hoefer, Bianca, Greben, Kyrylo, Libisch, Florian, Bolotin, Kirill I.

Mechanical strain is a powerful tuning knob for excitons, Coulomb-bound electron-hole complexes dominating optical properties of two-dimensional semiconductors. While the strain response of bright free excitons is broadly understood, the behavior of
