Electronic structures based on spectral characterizations. a, b Mott-Schottky plots of 2DPA (a) and 2DA (b). V is the applied bias at the electrode, and C is the obtained capacitance. c, d Absorbance spectra, VB XPS spectra of 2DPA (purple) and 2DA (orange). e Schematic illustration of the band structures. The cyan lines represent Fermi levels, and the numbers above mean the Fermi level positions. The light purple bands represent CBs and VBs, and the numbers inside mean the values of CBMs and VBMs
