TIEG - Terrassa Industrial Electronics Group

 

El grupo emergente TIEG surge a raíz de la investigación realizada por varios integrantes doctores y no doctores del grupo 2014 SGR-577. El grupo ha realizado colaboraciones y está en contacto con varias empresas del sector de renovables, tracción y electrodomésticos. Las inquietudes planteadas por dichas empresas al grupo, para hacer sus productos más eficientes y fiables con el uso de nuevos dispositivos semiconductores de amplia banda prohibida WBG), han dado lugar a esta petición.
