Qin Zhang, Guangle Zhou, Huili G. Xing, Alan C. Seabaugh, Kun Xu, Sio Hong, Oleg A. Kirillov, Curt A. Richter, Nhan Van Nguyen
The electron energy band alignment of a metal-oxide-semiconductor tunnel field-effect transistor (TFET) heterojunction, W/Al2O3/InGaAs/InAs/InP is determined by internal photoemission spectroscopy. At the oxide flat-band condition, the barrier height from

Hydrogen Species Motion in Piezoelectrics: A Quasi-Elastic Neutron Scattering Study

K. J. Alvine, Madhu Sudan Tyagi, Craig Brown, Terrence J. Udovic, T. Jenkins, S. G. Pitman
Hydrogen is known to damage or degrade piezoelectric materials, at low pressure for ferroelectric random access memory applications, and at high pressure for hydrogen powered vehicle applications. The piezoelectric degradation is in part governed by the
