Dr. Jose PIÑERO is Lecturer in mathematics at University of Cadiz, with a PhD in Semiconductor Physics (2016). His research activities are focused on:  (i) the role of the interfaces and terminations in diamond power devices, studying diamond heterojunctions by a variety of techniques; (ii) the effects of the ion-implantation in diamond; (iii) opto-electronic behavior of diamond; (iv) nano-characterization of other III-V semiconductors. He carried out his PhD work as well as research stays in EPFL-Lausanne (Switzerland) and Institut Néel in Grenoble (France) on cathodoluminescence of semiconducting materials as for example homoepitaxial diamond structures.
