We present a fast method to fabricate high quality heterostructure devices by picking up crystals of arbitrary sizes. Bilayer graphene is encapsulated with hexagonal boron nitride to demonstrate this approach, showing good electronic quality with mobilities ranging from 17 000 cm2 V−1 s−1 at room temperature to 49 000 cm2 V−1 s−1 at 4.2 K, and entering the quantum Hall regime below 0.5 T. This method provides a strong and useful tool for the fabrication of future high quality layered crystal…

Scanning tunnelling microscopy and spectroscopy of ultra-flat graphene on hexagonal boron nitride.
Scanning tunnelling microscopy is used to show that graphene conforms to hBN, as evidenced by the presence of Moiré patterns, but contrary to predictions, this conformation does not lead to a sizeable band gap because of the misalignment of the lattices.
