Low temperature STM on InAs (110) accumulation surfaces

Mesoscale and Nanoscale Physics 2009-09-25 v2 Materials Science

Abstract

The properties of InAs (110) surfaces have been investigated by means of low-temperature scanning tunneling microscopy and spectroscopy. A technique for ex-situ sulphur passivation has been developed to form an accumulation layer on such a surface. Tunneling spectroscopy at 4.2 K shows the presence of 2D subbands in the accumulation layer. Measurements in high-magnetic field demonstrate Landau quantization of the energy spectrum, both in the 2D subbands and the 3D bulk conduction band.
