Extended Data Fig. 1: IETS device with Gr contacts.
From: Magnetic anisotropy reversal driven by structural symmetry-breaking in monolayer α-RuCl3
(a): Colorized optical image of the sample. The device is fabricated in the same geometry as shown in Fig. 1a, except the Td-MoTe2 is replaced by few-layer graphene and the thickness of α-RuCl3 is 5-6 layers. (b): False-color two-dimensional plot of background-subtracted d2I/dV2 spectrum taken from 0.3 K to 10 K for positive bias. The trace at 0.3 K is overlaid in blue. The low-energy peak at 1 meV is reproduced in this sample, which gradually disappears above ~8 K, and the continuum between 4-10 meV is reproduced as well.
