Carlos García Núñez received his BSc in Physics in 2009, and MSc in Advanced Materials and Nanotechnology in 2010 from Universidad Autónoma de Madrid (Spain). In 2015, he completed his PhD in Physics in the Applied Physics Department at Universidad Autónoma de Madrid (Spain), investigating the growth of III-V and II-VI nanowires by chemical beam epitaxy and chemical vapor transport techniques. He is currently working as Postdoctoral Researcher in Bendable Electronics and Bendable Electronics (BEST) Group in the School of Engineering at the University of Glasgow (UK), developing flexible electronic-skin based on semiconductor nanowires and graphene.
In 2009, I received my BSc in Physics from Universidad Autónoma de Madrid (UAM). One year later, I finished my MSc in Advanced Materials and Nanotechnology at the Department of Applied Physics (UAM). My MSc project was about the growth and doping of GaAs thin films deposited by Chemical Beam Epitaxy (CBE) for solar cell applications. This work was carried out under the supervision of Prof. B.J. García.
In 2010, I joined the Group of Electronics and Semiconductors (ELySE) under the supervision of Full Prof. J. Piqueras. During that time, I worked in the project namely AVANSENS, exploring novel technologies to develop gas- and bio-sensing advanced platforms, as well as, photodetectors based on semiconductors with the shape of thin films and deposited by sputtering techniques. In that project, I investigated earth-abundant materials such as zinc nitride (Zn3N2) as a channel layer in electronic devices, including thin film transistors (TFTs) and photo-transistors.

In 2011, I became a Fellowship Researcher (FPI, Spanish MINECO) at ELySE (Department of Applied Physics, UAM). The project was about the design and fabrication of photodetectors based on zinc oxide (ZnO) and gallium arsenide (GaAs) nanowires (NWs). In this regard, the project comprised the growth of both ZnO and GaAs NWs by Chemical Vapor Transport (CVT) and CBE, respectively, their characterization, and finally their integration in electronic devices. The assembly of NWs between conductive electrodes separated a micrometric distance was carried out by using non-uniform electric fields, which is known as dielectrophoresis.

In 2015, I obtained my PhD in physics (summa “cum laude”). In October 2015, I joined the Bendable Electronics and Sensing Technologies (BEST) Group, as a postdoctoral research assistant, at the University of Glasgow (UK), where I am currently developing my research work. In this group, I am participating actively in the integration of semiconductor nanowires and two-dimensional materials such as single layer graphene on flexible substrates via transfer printing and hot-lamination techniques, respectively. The main aim of this research work is to develop high-performance electronic skin (e-skin) for robotics and smart prostheses.
