Dr Carlos Garcia Nunez
- Research Assistant (Systems Power and Energy)
Carlos Garcia Nuñez is a Postdoctoral Research Assistant in the group of Bendable Electronics and Sensing Technologies (BEST) at the University of Glasgow. In 2009, he received a B.S. degree in Physics from the Universidad Autonoma de Madrid (UAM). One year later, he finished a M.S. in Advanced Materials and Nanotechnology at the Department of Applied Physics (UAM). In 2010, he joined the group of Electronics and Semiconductors (ELySE) at UAM, and one year later he became a Fellowship Researcher (Spanish FPI MINECO fellowship) at ELySE. In 2015, he obtained a Ph.D in physics (summa "cum laude") entitled "Contribution to the Development of Electronic Devices Based on Zn3N2 Thin Films, and ZnO and GaAs Nanowires."
He has published above 30 articles – 25 as first author – in Journals and peer-reviewed International Conferences, 1 book chapter and 1 patent. He regularly assists to international conferences to give lectures (so far, 2 per year). He has actively participated in multidisciplinary research projects, including sensors and biosensors based on earth abundant materials such as Zn3N2, IR/VIS/UV photodetectors based on ZnO and Ga(As,N) nanowires, and multi-band solar cells. He carried out two visiting researches for three months at The University of Alabama (characterization of GaAs nanowires by TEM and Raman spectroscopy), and The Walter Schottky Institut (fabrication of functionalized ZnO nanowires based liquid gate field effect transistors). From both stays, he has published 4 peer-reviewed journal articles – all as first author – which points out his initiative, capacity to learn new knowledge and work in new environments, and skills to solve individually issues found during every research project.
His current multidisciplinary research interests comprise the development of electronics on non-conventional substrates, including flexible and wearable electronics. He is working on the development of an electronic skin (e-skin), which comprises transparent and flexible touch sensors based on single layer graphene, and nanowire based flexible electronics. The development of the transparent and flexible e-skin will allow robotic limbs to have touch sensitivity, being the tactile feedback crucial, for example, for the controlled grabbing of objects. He also develops low-power consumption and high-efficiency flexible electronics based on different semiconductor nanowires, including IV-group and metal oxide materials. In this regard, he investigate new techniques for high-performance transfer of crystalline nanowires from the growth substrate to non-conventional substrates, comprising techniques such as contact printing and dielectrophoresis.
He is an expert in multidisciplinary fields including physics, chemistry and engineering:
- Nanowire synthesis by chemical beam epitaxy (CBE) and vapor phase transport (VPT).
- Nanowire integration by contact-transfer printing, roll-printing, and dielectrophoresis.
- Micro- and nano-fabrication in clean room of electronic devices (gas-, liquid-, and light sensors based on single and multi-nanowires).
- Growth and characterization of semiconductor materials (earth-abundant and III-V materials).
- Fabrication and characterization of capacitive touch sensors based on graphene.
