Non-invasive digital etching of van der Waals semiconductors
Jian Zhou, Chunchen Zhang, Li Shi +12
The capability to finely tailor material thickness with simultaneous atomic precision and non-invasivity would be useful for constructing quantum platforms and post-Moore microelec…
Clean BN encapsulated 2D FETs with lithography compatible contacts
Binxi Liang, Anjian Wang, Jian Zhou +6
Device passivation through ultraclean hexagonal BN encapsulation is proven one of the most effective ways for constructing high-quality devices with atomically thin semiconductors…
Coupled Ferroelectricity and Superconductivity in Bilayer -MoTe
Apoorv Jindal, Amartyajyoti Saha, Zizhong Li +8
Achieving electrostatic control of quantum phases is at the frontier of condensed matter research. Recent investigations have revealed superconductivity tunable by electrostatic do…
Spontaneous momentum polarization and diodicity in Bernal bilayer graphene
Jiang-Xiazi Lin, Yibang Wang, Naiyuan J. Zhang +4
The low-temperature phase diagram of multilayer graphene heterostructures is largely defined by the exchange-driven instability that lifts the four-fold isospin degeneracy. Such in…
Interface engineering of charge-transfer excitons in 2D lateral heterostructures
Roberto Rosati, Ioannis Paradisanos, Libai Huang +9
The existence of bound charge transfer (CT) excitons at the interface of monolayer lateral heterojunctions has been debated in literature, but contrary to the case of interlayer ex…
Specular electron focusing between gate-defined quantum point contacts in bilayer graphene
Josep Ingla-Aynés, Antonio L. R. Manesco, Talieh S. Ghiasi +4
We report on multiterminal measurements in a ballistic bilayer graphene (BLG) channel where multiple spin and valley-degenerate quantum point contacts (QPCs) are defined by electro…
