The semiconducting surface of In$_{4}$Se$_{3 }$

ORAL

Abstract

The layered crystal In$_{4}$Se$_{3}$ is of growing interest because of its natural two dimensional structure and anomalies concerning transport properties. We have studied both the lattice and electronic band structures of cleaved (001) surface of In$_{4}$Se$_{3}$. Both LEED and STM reveal a $p$(1$\times $1) surface structure with quasi-one dimensional atomic chains. ARPES data also confirm such quasi-one dimensional character with a very anisotropic band structure. The surface electronic density of states measured by tunneling spectroscopy is compared with theoretical calculations.
