- 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.
♦ Atomic Force Microscopy (AFM): AFM Veeco diMultimode V, NanoSurf easyScan 2
♦ Scanning Electron Microscopy (SEM): STEM, Hitachi, S-5500 S(T)EM, Fe-SEM (Zeiss Ultra 55 LE), LV-Fe-SEM (Zeiss Supra 55 VP)
♦ Focused ion beam (FIB): FEI Helios Nanolab
♦ Transmission Electron Microscopy (TEM): Performed analysis of the TEM data.
♦ Light Microscopy
♦ X-ray Photoelectron Spectroscopy (XPS): Kratos AXIS Ultra DLD, also joined in the resonant photoelectron spectroscopy (RPES) of ZnS:Cr using Mat-line of the synchrotron radiation ASTRID2 in Aarhus.
♦ Optical UV-VIS
♦ Energy Dispersive X-ray Spectroscopy (EDS): EDS on the SEM setups
- Solar cell (device) characterization:
♦ I-V characteristics
♦ Quantum efficiency
- Other experience:
♦ X-ray diffraction (XRD)
♦ 4-point probe: conductivity measurement
♦ Wafer scriber
♦ Glove box
♦ Extensive working experience in cleanroom ISO 5 and ISO 7
♦ Theoretical and practical experience in design and maintenance of vacuum systems, specifically pulsed laser deposition system.
