    • On Modern IGBT Modules: Characterization, Reliability and Failure Mechanisms 

      Xiao, Di (Master thesis, 2010)
      The increased demand of offshore power conversion systems is driven by newly initiated offshore projects for wind farms and oil production. Because of long distances to shore and inaccessibility of the equipment long repair ...

    • Terahertz Antiferromagnetic Spin Hall Nano-Oscillator 

      Cheng, Ran; Xiao, Di; Brataas, Arne (Journal article; Peer reviewed, 2016)
      We consider the current-induced dynamics of insulating antiferromagnets in a spin Hall geometry. Sufficiently large in-plane currents perpendicular to the Néel order trigger spontaneous oscillations at frequencies between ...
