Abstract

Auger electron spectroscopy (AES) and electron loss spectroscopy (ELS) have been performed in order to investigate InP (100) surfaces subjected to a controlled Sb deposition.

The combination of these two electron spectroscopies and a fine analysis of AES signals as a function of surface coverage allows us to propose a model for the formation of Sb/InP interfaces.

Indium droplets present on the sample after Ar^+^cleaning disappear during the first Sb deposit to form an InSb surface compound, which gives the surface great stability.

If the deposit is formed at a high temperature after this first stage, no more Sb atoms can be condensed, whereas at room temperature the growth mode is of the Franck Van Der Merwe type.
