Peter Hadley received a B.S degree in Applied and Engineering Physics from Cornell in 1982 and a PhD in Applied Physics from Stanford in 1989. His PhD thesis was entitled, 'The dynamics of Josephson junction arrays.' He then moved to the Technical Physics department of the Delft University of Technology in Delft, The Netherlands. There he investigated superconducting circuits, single-electron circuits, carbon nanotube and single-molecule devices, as well as organic semiconductor devices. In 2006 he was appointed the director of the Institute of Solid State Physics at Graz University of Technology in Graz, Austria.

The focus of my research is semiconductor materials and devices. Often defects play an important role in determining the properties of semiconductors. Defects are also primarily responsible for degradation effects that influence device reliability. Most of the projects are done in collaboration with industrial partners. Southern Austria has a vibrant semiconductor industry, an overview of which can be found on the Silicon Alps website. Companies such as Infineon in Villach or ams-OSRAM in Premstaetten have much better semiconductor fabrication equipment than a university could afford and there are many scientists in these companies with a deep knowledge of materials and processes. To keep up in the rapidly evolving microelectronics field, the companies invest heavily in research and development and they finance many master and PhD positions. Ideally, the master and PhD students joint a team that is pursuing long term or exploratory research when the companies have more advantage from sharing their results with the international scientific community than keeping their results confidential.

Below is a list of PhD and master theses I have supervised that were completed in cooperation with Infineon, asm-OSRAM, IBM, Austrian Institute of Technology, Fraunhofer Institute, Joanneum Research, or Kompetenzzentrum Automobil- und Industrie-Elektronik.
