TL;DR: This work reports on the search for alternative substrates for making quality graphene heterostructures using atomically flat crystals and attributes the difference mainly to self-cleansing that takes place at interfaces between graphene, hBN, and transition metal dichalcogenides.

TL;DR: It is demonstrated how careful alignment of the crystallographic orientation of two graphene electrodes separated by a layer of hexagonal boron nitride in a transistor device can achieve resonant tunnelling with conservation of electron energy, momentum and, potentially, chirality.

TL;DR: In this article, the Hofstadter butterfly is suppressed by suppression of quantum Hall antiferromagnetism at particular commensurate magnetic fluxes by means of capacitance spectroscopy.

TL;DR: The direct observation and manipulation of chirality and pseudospin polarization in the tunneling of electrons between two almost perfectly aligned graphene crystals are reported and a technique for preparing graphene’s Dirac electrons in a particular quantum chiral state in a selected valley is demonstrated.

TL;DR: In this article, the authors report on the search for alternative substrates for making quality graphene heterostructures, using molybdenum or tungsten disulphides and hBN.
