Raul Ramos

Conducted research in the field of transparent conductive oxides with wide gap semiconductor. He produced his samples in Photovoltaic Research Laboratory, Department of Applied Physics at the Institute of Physics Gleb Wataghin (Unicamp) by Ion Beam Deposition and in ICTS (Sorocaba Institute of Science and Technology) at Sao Paulo State University (UNESP) by Magnetron Sputtering. Performed measures concerning the chemical composition and bonding states through XPS (X-Ray Photoeletron Spectroscopy) and EDS (Energy-Dispersive X-ray Spectroscopy), structural and morphological characterization by XRD (X-Ray Diffraction), SEM (Scanning Electron Microscope) and AFM (Atomic Force Microscope) techniques, electrical properties by Hall effect and linear 4-probe method, optical properties by UV-Vis-NIR Spectroscopy.
