Abstract
In recent years we have dedicated to the investigation of transport properties of the heterojunction SnO2 / GaAs, which has opened possibilities to several specific projects. In this context this PhD project can be suited, being divided into two lines of research: 1) Deposition of heterojunction of SnO2 with GaAs, where the SnO2 can be pure or doped with rare-earth ions, such as Er3 + or …
