Structural and energy changes at the cleavage surfaces of In₄Se₃ layered crystals under interface formation

Structural and energy changes at the cleavage surfaces of In₄Se₃ layered crystals during interface formation have been studied by means of the ultraviolet photo-electron spectroscopy (UPS) and low-energy electron diffraction. The unintentionally doped In₄Se₃ crystal cleavages exposed to atmosphere o...
