Research interests

Professor Udrea’s first field of research is in the field of high voltage technologies and power devices There are several  themes in this field, including:

  • vertical power devices such as Power MOSFETs, Superjunctions, Insulated Gate Bipolar Transistors(IGBTs), Gate Turn-off and Gate Commuted Thyristors
  • lateral power devices for Power and High Voltage ICs, including LDMOSFETs, Resurf and Superjunction devices and LIGBTs, SOI power devices
  • Wide bandgap materials and devices such as GaN High Electron Mobility Transistors (HEMTs), Silicon Carbide JFETs and MOSFETs and Diamond power devices

Professor Udrea’s second field of research is in the field of MEMS and microsensors. The most important aspects of his research are:

  • CMOS based gas sensors using micro-hotplates
