Radio-frequency charge detection on graphene electron-hole double quantum dots
Katrin Hecker, Samuel Möller, Hubert Dulisch +10
High-fidelity detection of charge transitions in quantum dots (QDs) is a key ingredient in solid state quantum computation. We demonstrate high-bandwidth radio-frequency charge det…
Strain engineering of valley-polarized hybrid excitons in a 2D semiconductor
Abhijeet M. Kumar, Douglas J. Bock, Denis Yagodkin +11
Encoding and manipulating digital information in quantum degrees of freedom is one of the major challenges of today's science and technology. The valley indices of excitons in tran…
Current-induced brightening of vacancy-related emitters in hexagonal boron nitride
Corinne Steiner, Rebecca Rahmel, Frank Volmer +9
We perform photoluminescence measurements on vacancy-related emitters in hexagonal boron nitride (hBN) that are notorious for their low quantum yields. The gating of these emitters…
Negative electronic compressibility in charge islands in twisted bilayer graphene
Robin J. Dolleman, Alexander Rothstein, Ammon Fischer +8
We report on the observation of negative electronic compressibility in twisted bilayer graphene for Fermi energies close to insulating states. To observe this negative compressibil…
Band gap formation in commensurate twisted bilayer graphene/hBN moiré lattices
Alexander Rothstein, Christoph Schattauer, Robin J. Dolleman +8
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 hexagon…
