In 2009, Carlos García Núñez received the B.S. degree in physics at the Universidad Autónoma de Madrid (UAM). One year later, he finished the M.S. in Advanced Materials and Nanotechnology at the Department of Applied Physics (UAM). His M.S. 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, he joined the Group of Electronics and Semiconductors (ELySE) under the supervision of Full Prof. J. Piqueras. During that time, he was working in the AVANSENS project, exploring novel technologies to develop gas- and bio-sensing advanced platforms, as well as, photodetectors. In that project, he investigated earth-abundant materials such as zinc nitride (Zn3N2) as channel layer in electronic devices, including thin film transistors (TFTs) and photo-transistors.

In 2011, he became a Fellowship Researcher (FPI fellowship belonging to the MINECO-Spain) 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 comprises 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 field, which is known as dielectrophoresis.

In 2015, he obtained the PhD in physics (summa “cum laude”). In October 2015, he joined as postdoctoral assistant researcher in the Group of Bendable Electronics and Sensing Technologies (BEST) at the University of Glasgow (UK), where he is currently developing his research work. In this group, he is 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, respectively. The main aim of his research work is to develop high performance electronic skin (e-skin) for robotics and smart prostheses.
