Fig. 1

a Schematic representation of the InPSe in the side view. b EDS spectrum was obtained from the bulk crystals. The table in the inset indicates a stoichiometry ratio of the crystal flakes. c A high-resolution TEM (HRTEM) image of the flake and the scale bar is 5 nm. The inset shows the SAED patterns obtained from the HRTEM image and the scale bar is 51/nm. d PL and Raman spectra of the flake. The insets show the optical image of the exfoliated flake and its corresponding PL mapping at 674 nm and the scale bar is 5 µm.
