Light-emitting diodes by bandstructure engineering in van der Waals heterostructures
F. Withers, O. Del Pozo-Zamudio, A. Mishchenko +8
The advent of graphene and related 2D materials has recently led to a new technology: heterostructures based on these atomically thin crystals. The paradigm proved itself extremely…
Heterostructures produced from nanosheet-based inks
F. Withers, H. Yang, L. Britnell +13
The new paradigm of heterostructures based on two-dimensional (2D) atomic crystals has already led to the observation of exciting physical phenomena and creation of novel devices.…
Detecting Topological Currents in Graphene Superlattices
R. V. Gorbachev, J. C. W. Song, G. L. Yu +8
Topological materials may exhibit Hall-like currents flowing transversely to the applied electric field even in the absence of a magnetic field. In graphene superlattices, which ha…
Two-dimensional metal-chalcogenide films in tunable optical microcavities
S. Schwarz, S. Dufferwiel, P. M. Walker +12
Quasi-two-dimensional (2D) films of layered metal-chalcogenides have attractive optoelectronic properties. However, photonic applications of thin films may be limited owing to weak…
Hierarchy of Hofstadter states and replica quantum Hall ferromagnetism in graphene superlattices
G. L. Yu, R. V. Gorbachev, J. S. Tu +16
Self-similarity and fractals have fascinated researchers across various disciplines. In graphene placed on boron nitride and subjected to a magnetic field, self-similarity appears…
Electronic Properties of Graphene Encapsulated with Different Two-Dimensional Atomic Crystals
A. V. Kretinin, Y. Cao, J. S. Tu +18
Hexagonal boron nitride is the only substrate that has so far allowed graphene devices exhibiting micron-scale ballistic transport. Can other atomically flat crystals be used as su…
