Colloquium: Spintronics in graphene and other two-dimensional materials
A. Avsar, H. Ochoa, F. Guinea +3
After the first unequivocal demonstration of spin transport in graphene (Tombros et al., 2007), surprisingly at room temperature, it was quickly realized that this novel material w…
Direct observation of water mediated single proton transport between hBN surface defects
Jean Comtet, Benoit Grosjean, Evgenii Glushkov +6
Aqueous proton transport at interfaces is ubiquitous and crucial for a number of fields, ranging from cellular transport and signaling, to catalysis and membrane science. However,…
Control of interlayer excitons in two-dimensional van der Waals heterostructures
Alberto Ciarrocchi, Dmitrii Unuchek, Ahmet Avsar +3
Long-lived interlayer excitons with distinct spin-valley physics in van der Waals heterostructures based on transition metal dichalcogenides make them promising for information pro…
van der Waals Bonded Co/h-BN Contacts to Ultrathin Black Phosphorus Devices
Ahmet Avsar, Jun Y. Tan, Luo Xin +6
Due to the chemical inertness of 2D hexagonal-Boron Nitride (h-BN), few atomic-layer h-BN is often used to encapsulate air-sensitive 2D crystals such as Black Phosphorus (BP). Howe…
