The research group on electron devices (TIC105-GRIDE) began its activity in January 1985. In its initial phase, the group set up a laboratory for semiconductor device characterization and started its activity in the characterization, modeling, and simulation of electron devices, with a focus on the study of electronic states, transport of charge carriers, and noise. Its initial coordinator was Prof. Pedro Cartujo Estébanez, who was replaced by Prof. Juan Enrique Carceller Beltrán in 2006. Prof. Juan Antonio López Villanueva has been in charge of the group since 2023.
After rapid early growth, some of its members started new research groups in such a way that the TIC105 group has been the germ of four officially constituted groups today. Later on, its research activity was progressively diversified, including the modeling of structures made with organic semiconductors and the effects of ionizing radiation on field effect transistors with application in clinical dosimetry, and it incorporated new lines on sensors and instrumentation systems and devices for energy generation, such as multi-junction, organic, perovskite, and quantum dot-based solar cells. More recently, a new research line has been started on energy storage devices, with a current focus on the modeling of lithium-ion batteries. There are doctoral theses currently underway in all of the aforementioned lines of work.
Several researchers from the TIC105 group are also a part of the interdisciplinary group ECsens in the field of instrumentation systems. Along with researchers from the FQM118 group and members of other groups on electronics and telecommunications engineering, chemistry and computer science, they work on numerous research and transfer projects on various topics, with a special dedication to printed sensors for in-situ chemical analysis in conjunction with the use of smartphones.
The TIC105 group has developed its activity in collaboration with other groups, both from the University of Granada and from other national and international centers. The group's researchers have participated in numerous national and European research projects, have published plenty of articles in scientific journals of high international impact, have presented papers and given invited talks at major congresses and conferences, have also developed numerous technology transfer projects with companies, and they participate in a spin-off company of the University of Granada. Recently, researchers from the TIC105 group participate in and direct two business-sponsored chairs with companies Valeo Iluminación (Valeo-UGR Chair on quantum-scale science) and MFS IDI (Electronics Chair on efficiency, electrification and sustainable energy).
