Effects of external surface charges on the enhanced piezoelectric potential of ZnO and AlN nanowires and nanotubes
We theoretically investigate external surface charge effects on piezoelectric potential of ZnO and AlN nanowires (NWs) and nanotubes (NTs) under uniform compression. The free carrier depletion caused by negative surface charges via surface functionalization on vertically compressed ZnO and AlN NWs/N...
