title: Polymorphic transformation of dense ZnO nanoparticles: implications for chair/boat-type Peierls distortions of AB semiconductor.
abstract: Peierls distortion path was proved experimentally for dense ZnO nanoparticles prepared by static compression. Electron irradiation caused rock salt (R) to wurtzite (W) transition, following preferential (111)(R)//(0111)(W); [011](R)//[1213](W) and then transformation strain induced (111)(R)//(1011)(W); [011](R)//[0111](W). The two relationships can be rationalized by specified extent of chair- and boat-type Peierls distortions accompanied with band gap opening and intermediate {111}R slip for energetically favorable {111}R/(0111)W match.
