DESCRIPTION:Cornell Electron Devices Society (EDS) presents:\n\nYuhao Zhang
 \nVirginia Tech\n\nMultidimensional Devices: Reshaping the Power Electroni
 cs Landscape\n\nAbstract\nPower electronics technologies provide electrica
 l energy conversion using semiconductor devices and passive components. Th
 e global power device market reaches US$40 billion and is rapidly expandin
 g\, driven by applications like electric vehicles\, data centers\, consume
 r electronics\, electric grids\, and renewable energy processing.\n\nPower
  device advances are driven by materials and device architectures. In addi
 tion to using wide- or ultrawide-bandgap materials\, multidimensional arch
 itectures – such as superjunctions\, multi-channels\, and multi-gates 
 – can also improve device performance\, regardless of the underlying mat
 erial technology. These structures enable electrostatics engineering in ad
 ditional dimensions and bring the benefits of geometrical scaling into pow
 er devices.\n\nThis talk presents our efforts in developing multidimension
 al power devices in gallium nitride (GaN)\, which have set several new rec
 ords in power device performance and thus expanded the GaN’s application
  space from 10 V to 10 kV. These devices hold great potential for advancin
 g the speed\, efficiency\, and form factor of power electronics systems\, 
 and some of them are currently being commercialized. Our work on packaging
 \, thermal management\, and device reliability/robustness evaluation will 
 also be introduced\, all of which are essential to exploiting the breakthr
 ough device performance in power electronics systems.  \n\nBio\nDr. Yuhao 
 Zhang is an assistant professor at the Center for Power Electronics System
 s (CPES)\, the Bradley Department of Electrical and Computer Engineering\,
  Virginia Tech. He leads the power semiconductor research at CPES\, one of
  the largest university-based power electronics research centers in the U.
 S. Before joining CPES in 2018\, he worked as a postdoctoral associate at 
 the Massachusetts Institute of Technology (MIT) from 2017 to 2018. He rece
 ived his Ph. D. and S. M. in electrical engineering from MIT in 2017 and 2
 013\, respectively. Before joining MIT\, he received his B. S. in physics 
 from Peking University in 2011. His research interest is at the intersecti
 on of power electronics\, microelectronic devices\, and advanced materials
 . He has authored over 100 journal papers (EDL\, T-ED\, T-PEL\, Nature\, N
 ature Electronics\, etc.) and conference proceedings (IEDM\, ISPSD\, IRPS\
 , APEC\, etc.) and holds 5 granted U. S. patents. He received the MIT Micr
 osystems Technology Laboratories Doctoral Dissertation Award in 2017\, the
  IEEE George Smith Award in 2019\, the National Science Foundation CAREER 
 Award in 2021\, the Outstanding New Assistant Professor Award of Virginia 
 Tech Engineering in 2021\, and the Faculty Fellow Award of Virginia Tech E
 ngineering in 2022.
