发帖数: 39 | 1 Professor Zhong Lin Wang’s group at Georgia Tech has a postdoctoral opening
in the field of piezotronics and piezo-phototroncis. Due to the
polarization of ions in a crystal that has non-central symmetry in materials
such as the wurtzite structured ZnO, GaN and InN, a piezoelectric potential
(piezopotential) is created in the crystal by applying a stress. Owing to
the simultaneous possession of piezoelectricity and semiconductor properties
, the piezopotential created in the crystal has a strong effect on the
carrier transport at the interface/junction. Piezotronics is about the
devices fabricated using the piezopotential as a “gate” voltage to tune/
control charge carrier transport at a contact or junction. Piezo-phototronic
effect is to use the piezopotential to control the carrier generation,
transport, separation and/or recombination for improving the performance of
optoelectronic devices, such as photon detector, solar cell and LED. By
integrating piezotronic and piezo-phototronic devices with silicon based
CMOS technology, unique applications can be found in areas such as human-
machine interfacing, sensing and actuating in nanorobotics, smart and
personalized electronic signatures, smart MEMS/NEMS, nanorobotics and energy
sciences.
The postdoctoral fellow is expected to have a PhD degree in electric
engineering, physics or materials science, but must have a solid record in
electronic and photonic devices, nano-scale fabrications and measurements.
The interested parties can send CV, a statement of research and 3 letters of
