Abstract
The work involves the production and the electrical and optical characterization of thin films in different stages. Step 1) Deposition of SnO2 and GaAs, and heterojunction GaAs/SnO2: a) SnO2 doped with rare-earth ions, deposited via sol-gel-dip-coating, b) GaAs. It will be done the incorporation of the rare-earth dopant in the semiconductor matrix oxide (SnO2), where they present high emi…
