Pablo Thiago Valentim

Research Fellow
Microfabrication and Exploratory Nanotechnology

Pablo joined the group of Microfabrication and Exploratory Nanotechnology at INL where he will explore the techniques of plasma-enhanced chemical vapor deposition to grow thin layers of semiconductor materials onto polymeric lenses and use reflectivity experiments to characterize the device’s properties.

He holds a PhD in Physics by the Universidade Federal de Minas Gerais (Brazil, 2006-2013) and postdoctoral experiences at the Universidade Federal de Minas Gerais (Brazil, 2014 and 2016) and at the International Iberian Nanotechnology Laboratory (Portugal, 2015). His experience in research gathers the study of photonic cavities of AlGaAs/GaAs, silicon nitride and quantum dots, using microphotoluminescence and reflectivity techniques. He also has experience in lithographic processes of micro and nanofabrication of silicon nitride and silicon dioxide optical devices.
