Gap Opening in Twisted Double Bilayer Graphene by Crystal fields
Peter Rickhaus, Giulia Zheng, Jose L. Lado +12
Crystal fields occur due to a potential difference between chemically different atomic species. In Van-der-Waals heterostructures such fields are naturally present perpendicular to…
Tunable Valley Splitting due to Topological Orbital Magnetic Moment in Bilayer Graphene Quantum Point Contacts
Yongjin Lee, Angelika Knothe, Hiske Overweg +10
In multivalley semiconductors, the valley degree of freedom can be potentially used to store, manipulate and read quantum information, but its control remains challenging. The vall…
Fully automated identification of 2D material samples
Eliska Greplova, Carolin Gold, Benedikt Kratochwil +7
Thin nanomaterials are key constituents of modern quantum technologies and materials research. Identifying specimens of these materials with properties required for the development…
The Electronic Thickness of Graphene
Peter Rickhaus, Ming-Hao Liu, Marcin Kurpas +10
The van-der-Waals stacking technique enables the fabrication of heterostructures, where two conducting layers are atomically close. In this case, the finite layer thickness matters…
Excited states in bilayer graphene quantum dots
A. Kurzmann, M. Eich, H. Overweg +11
We report on ground- and excited state transport through an electrostatically defined few-hole quantum dot in bilayer graphene in both parallel and perpendicular applied magnetic f…
Charge detection in gate-defined bilayer graphene quantum dots
A. Kurzmann, H. Overweg, M. Eich +8
We report on charge detection in electrostatically-defined quantum dot devices in bilayer graphene using an integrated charge detector. The device is fabricated without any etching…
