15 صفحه اولPreface to the special section on piezotronics.
For wurtzite structures that have noncentral symmetry, such as ZnO, GaN and InN, a piezoelectric potential (piezopotential) is created in the crystal by applying a strain. Owing to the semiconducting and piezoelectric properties of the wurtzite family, the strain-created inner-crystal piezopotential can serve as a “gate voltage” that can effectively tune/control the charge transport across an i...
