Skills and hands-on experience

  • Growth of metallic and semiconducting thin films:

Pulsed Laser Deposition (PLD): over seven years of experience in pulsed laser ablation and deposition of various semiconducting and oxide materials (Si, ZnS, ZnS:Cr, ZnO:Al, MoOx, WO3, TiO2, NiO, and binary compound oxides). Worked with two commercial (TSST and Neocera) ultra high vacuum, and one home-made high vacuum PLD systems.

 RF and DC Sputtering and E-beam Evaporation: applied to deposit metals such as Au, Al (sputtering), Ni, and Ti.

 Thermal Evaporation: applied to deposit ZnS, ZnS:Cu semiconductors and Pd, Zn, and Au as metal contacts for devices. Used two different costum-made systems.
