From: Modulation of Electronic and Optical Anisotropy Properties of ML-GaS by Vertical Electric Field
Partial density of states of the CBM and VBM of GaS ML without (a) and with (b) an external electric field of 8 V/nm, respectively. Spatial charge density difference and the vertical section along (1-100) plane of GaS ML without (c) and with (d) an external electric field of 8 V/nm, respectively. The positive and negative density (contours) are, respectively, shown with yellow (solid lines) and blue (dashed lines) colors, and the contour interval is 0.005 eÅ−3
