Recent News in our ALD Group:
"IEEE Spectrum" magazine, the most
prestigious one in electrical engineering society, publishes a long
feature article about our break-through work on ALD high-k/InGaAs MOSFET. This
article also reviews the history and current status of GaAs MOSFET research.
Science quotes our breakthrough work on
InGaAs MOSFET in its editorial article published on Feb. 20, 2009.
Three papers on InGaAs MOSFETs
