Thickness-dependent degradation and optical access in epitaxial 2H-MoTe2 protected by metallic capping layers
Wojciech Ryś, Iaroslav Lutsyk, Michał Piskorski +13
We investigate degradation and surface protection of epitaxial 2H-MoTe2 films grown by molecular beam epitaxy on GaAs(111)B substrates. Using X-ray photoelectron spectroscopy (XPS)…
Overcoming contact resistance at metal-2D semiconductor interfaces: atomically clean MoS2/Au ohmic junctions
Rafal Dunal, Maxime Le Ster, Iaroslav Lutsyk +8
The application of two-dimensional (2D) semiconductors, such as monolayer MoS2, is limited by the high contact resistance commonly attributed to interfacial barriers at metal conta…
Persistent spin texture preserved by local symmetry in graphene/WTe heterostructure
Przemyslaw Przybysz, Karma Tenzin, Berkay Kilic +4
Crystal symmetries in solids give rise to spin-momentum locking, which determines how an electron's spin orientation depends on its momentum. This relationship, often referred to a…
Evidence of directional structural superlubricity and Lévy flights in a van der Waals heterostructure
Maxime Le Ster, Paweł Krukowski, Maciej Rogala +11
Structural superlubricity is a special frictionless contact in which two crystals are in incommensurate arrangement such that relative in-plane translation is associated with vanis…
