Dr. Dazhen Gu received the B.S. degree in Physics
from Nanjing University, Nanjing,
China, in 1999, and M.S. and Ph.D degrees in Electrical Engineering
from University of Massachusetts Amherst
in 2004 and 2007.
From 1999 to 2001, he was a research assistant in the Superconductor Electronics
Laboratory of Nanjing University, where he worked on the three-terminal
device employing high-Tc fuperconductor, ferro-electric and ferro-magnetic materials.
Since 2001, he has been involved in the design and fabrication of NbN hot
electron bolometric mixer for terahertz receivers. Since November 2003, he
has worked at the Electromagnetics Division, National Institute of Standards and
Technology, Boulder, CO, where he is engaged in the development of
terahertz imaging systems and characterization of low noise amplifiers. His
research interest includes nano-fabrication, quantum electronics and RF
circuit design. Selected Publications D.Gu, E. Gerecht, F. Rodriguez-Morales, and S.
