Fig. 2: Electronic structure of the metastable state.
From: Revealing the electronic structure of the current-induced metastable state in 1T-TaS2
a Core level spectra of 1T-TaS2 in the CCDW (black) and metastable state (blue). b–d ARPES image plot along Γ-M direction in the pristine CCDW state at 12 K (b), in the metastable state after applying multiple current pulses (c), as well as after heating the metastable state to 90 K (d). e Energy distribution curves (EDCs) at Γ point for CCDW (black) and metastable (blue) state, as well as after heating to 90 K (green). Integration regions are shown in (c). f EDCs taken at −0.3Å−1, i.e., the region of the upper CDW gap. g, h Second derivative images of the CCDW (g) and metastable (h) state, respectively. To enhance visibility, images were smoothed using the Gaussian method over a window of 20 meV and 0.005Å−1. i, j Stacked EDCs taken between −0.27 and 0.27 Å−1for the CCDW (i) and the metastable state (j). For clarity, all EDCs are normalized to the same height.
