Fermi level pinning on (110) GaAs surfaces studied by CPD and SPV topographies
TL;DR: In this paper, contact potential difference (CPD) and surface photovoltage (SPV) have been associated in topographic (110) GaAs surfaces studied in n and p type samples.

Surface and contact properties of GaAs overlaid by silver
TL;DR: In this article, a study of the Schottky barrier formation on cleaved n and p-type GaAs through surface and contact measurements was made. The metal used was silver and the surface studies, performed using the Kelvin method, revealed that pinning of the Fermi level is obtained at submonolayer coverage and that silver deposition induced modifications in the electronic affinity.

Silver Schottky diodes on Kelvin, AES and LEED characterized (100)surfaces of GaAs cleaned by ion bombardment
TL;DR: In this paper, the Fermi level of all the surfaces was pinned in the midgap range and so there was, on both n and p types, an important surface barrier qVs whose value did not strongly depend on the surface preparations used.

Calculation of the work function of a substrate-thin film heterojunction
TL;DR: In this paper, a theoretical analysis of the work function of a semiconductor covered with a thin film was carried out, where the authors assumed that the layer was also a polysilicon and that there were no surface and interface states.

Sur la contribution du traitement de surface aux propriétés électroniques des surfaces réelles (100) de silicium type n
TL;DR: In this article, the effect of faisceau ionique and electronique on surfaces of the silicium type is investigated, and it is shown that electronique obtains a surface reproductible and homogene peu sensible.
