Jose Edgar Alfonso Orjuela
Jose Edgar Alfonso Orjuela earned his bachelor’s degree in Physics in 1987 and Magister degree in Physics in 1993; both titles were from Universidad Nacional de Colombia, and his PhD degree in Physics in 1997 was from Universidad Autónoma de Madrid (Spain). He has been working in materials science, especially in oxides of molybdenum and lithium niobate doped with rare earths. In these materials, he has studied the thermal coefficient expansion, luminescence emission, and magnetic behavior. His other works have focused on electrical and optical properties of materials grown in thin films. Currently, he is growing multifunctional films in order to characterize their optical and electrical properties.
