Fig. 1 A monolayer ReSe2 on a back-gated G/h-BN device. A monolayer ReSe2 on a back-gated G/h-BN device. (A) Schematic illustration of a back-gated ReSe2/graphene/h-BN device. (B) Top view of the atomic structure of monolayer ReSe2. The two lattice vectors (a and b) are outlined by red lines. The lattice constants are a = 6.6 Å and b = 6.7 Å. The angle between a and b is 118.9°. (C) A representative STM image of a monolayer ReSe2 flake on graphene/h-BN. Inset shows the STM line profile along the step edge. (D) Atomically resolved STM image of monolayer ReSe2. The STM image reveals the unique 1D chains consisting of diamond-shaped Re4 units along a direction (highlighted by orange line). The cross (X) marks the position where the differential conductance (dI/dV) spectra were taken. Zhizhan Qiu et al.
