From: NanoARPES of twisted bilayer graphene on SiC: absence of velocity renormalization for small angles

STM images of bilayer samples, (20 × 20 nm2) showing (a) non-moiré (I) and moiré (II) (7.3° twist angle) areas (−1 V sample bias, 50 pA tunneling current); moiré patterns with twist angles of (b) 1.5° and (c) 17.9°, (d) (3 × 3 nm2) STM image zoom of (c) showing the moiré superlattice (black unit cell), the graphene lattice (white unit cell) and the graphene honeycomb structure (blue), [(b–d) −2 V sample bias, 100 pA tunneling current], (e) scheme of the moiré in (d).
