George Junior

Research Engineer
Micro and Nanofabrication Facility

George Junior is a Research Engineer at INL, within the Microfabrication and Exploratory Nanotechnology group. He has a master degree in Physics and a PhD on Materials Engineering both from the University of Minho. During the master, he developed solar cells of amorphous silicon in flexible substrates. As a continuation of his master project, he works at INL on the period of 2010-2011 developing silicon solar cells. Next years, he was a teacher at Estácio de Sá University, Brazil.

He joined INL again in 2013 to pursue his PhD degree on microfabrication of graphene field-effect transistor for biosensing applications. He specialized on thin film deposition (graphene), transfer and characterization (mainly Raman spectroscopy), and on devices fabrication. During 2017, he worked at Cornell NanoScale Science and Technology Facility (CNF), Cornell University, developing graphene transistors for a spin-off project, as a researcher from UFMG, Brazil. He is currently developing the deposition of vertically-aligned carbon nanotubes at INL.
