Abstract

We measure the spatial variation of the local density of states normal to an InAs/GaSb heterointerface on a cleaved cross-sectional surface by low-temperature scanning tunneling spectroscopy. Clear standing waves originating from the interference between the incident and reflected electron waves at the interface are observed.
