Tunneling characteristics of twisted double bilayer graphene heterostructures
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +5
Electron tunneling between sheets of bilayer Bernal graphene twisted at different small angles was studied experimentally and theoretically. The current-voltage characteristics exh…
Probing the features of electron dispersion by tunneling between slightly twisted bilayer graphene sheets
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +6
Tunneling conductance between two bilayer graphene (BLG) sheets separated by 2 nm-thick insulating barrier was measured in two devices with the twist angles between BLGs less than…
Limiting performance of graphene bilayer sub-terahertz detectors at large induced band gap
Elena I. Titova, Mikhail A. Kashchenko, Andrey V. Miakonkikh +8
Electrically induced junctions in graphene bilayer (GBL) have shown superior performance for detection of sub-THz radiation at cryogenic temperatures, especially upon electri…
Infrared photodetection in graphene-based heterostructures: bolometric and thermoelectric effects at the tunneling barrier
Dmitry A. Mylnikov, Mikhail A. Kashchenko, Kirill N. Kapralov +7
Graphene/hBN/graphene tunnel devices offer promise as sensitive mid-infrared photodetectors but the microscopic origin underlying the photoresponse in them remains elusive. In this…
Twist-controlled resonant tunnelling in graphene-boron nitride-graphene heterostructures
A. Mishchenko, J. S. Tu, Y. Cao +19
Recent developments in the technology of van der Waals heterostructures made from two-dimensional atomic crystals have already led to the observation of new physical phenomena, suc…
