Fig. 3: Visualization of band structure spatial fluctuations by STS.
From: Giant persistent photoconductivity in monolayer MoS2 field-effect transistors
a STS data obtained at two different positions on MoS2/hBN/Pt(111) showing the onset values determined from the trapped states below the CB and above the VB. STS maps (50 nm × 50 nm) visualizing the spatial distribution of the band structure inhomogeneity are shown in (b) and (c), respectively (scale bar: 10 nm). The positions where the blue and green curves shown in a were obtained are marked with crosses. The corresponding topography map is provided in Supplementary Fig. 13.
