Description
Summary:	The furrowed structure of the surface lattice in accord with bulk crystallography data for non intentionally intercalated In 4 Se 3 crystal is also find to be the same for In 4 Se 3 silver intercalated crystal as it could be derived from scanning tunneling microscopy (STM) images of (100) surfaces. In 4 Se 3 (Ag) crystal surface doesn't show reconstruction after silver intercalation. Intercalated crystal's surfaces also reveal "dark and bright patches", associated with the presence or lack of intercalate due to scanning tunneling spectroscopy (STS) data. These different local areas on the cleavages show semiconductor and metallic nature. STS spectra allow us to determine the occurrence of an additional metallic component - silver, except, indium in the interlayer gap of the crystal on the local level. Auger electron spectroscopy records the presence of silver intercalate on macro scale. STM/STS data show on non-uniform intercalated silver distribution on the cleavage surface in nanoscale.
