A peeling approach for integrated manufacturing of large mono-layer h-BN crystals
Ruizhi Wang, David G. Purdie, Ye Fang +8
Hexagonal boron nitride (h-BN) is the only known material aside from graphite with a structure composed of simple, stable, non-corrugated atomically thin layers. While historically…
Graphene Reflectarray Metasurface for Terahertz Beam Steering and Phase Modulation
Michele Tamagnone, Santiago Capdevila, Antonio Lombardo +6
We report a THz reflectarray metasurface which uses graphene as active element to achieve beam steering, shaping and broadband phase modulation. This is based on the creation of a…
Cleaning Interfaces in Layered Materials Heterostructures
D. G. Purdie, N. M. Pugno, T. Taniguchi +3
Heterostructures formed by stacking layered materials require atomically clean interfaces. However, contaminants are usually trapped between the layers, aggregating into blisters.…
