Pedro Prieto Professor Pedro Prieto is the Director of the Excellence Center for Novel Materials in Colombia, as well as the Director of the Thin Films Group in the Department of Physics at the Universidad del Valle, Cali, Colombia. He holds a Physicist degree, in 1974 and a Magister Scientiae degree in Physics from Universidad Nacional de Colombia in 1978, working on Silicon Oxide Thin films. He received the “Doktor der Naturwissenschaften” Dr.rer.nat from Rheinische Westfaliche Hochschule RWTH-Aachen Germany in 1982 for the doctoral thesis: ¨Neutronenkleinwinkelstreuung an Guinier - Preston - Zonen in Aluminium - Kupfer - Legierungen¨ (Small Angle Neutron Scattering on Guinier-Preston Zones in AlCu Alloys). He joined the Universidad del Valle Cali, Colombia, in 1974 and became Full Professor in the Physics Department in 1986. Presently, he leads the Thin Films Research Group, which he established in 1978. Most of Prieto’s career has been devoted to R & D of materials science and electronic devices, particularly amorphous semiconductors, solar cells, High Temperature Superconductor materials, HTC Electronic Devices and Hard Coating Materials. The Thin Film laboratory began with the study of amorphous metallic alloys and through a COLCIECIAS research project (1983-1987) with Hydrogenated Amorphous-Si thin films. Since 1989, he has been working on the development of high-temperature superconductor devices based on superconducting thin films, in Magnetic materials in PZT - ferroelectric thin films and in Hard Coating Materials. Prof. Prieto has authored or co-authored over 100 scientific publications. He is an Alexander von Humboldt Fellow (1988), Guggenheim Fellow (1998) and American Physical Society Fellow (2000) “For forefront research in the Josephson Junction effect in high temperature superconductors and outstanding contribution to the development of physics in Latin America.”
