Oxide electronics, which together with amorphous semiconductors could become a rapid-growth field, have come a step closer with the first report of a p-type amorphous oxide semiconductor, ZnO·Rh2O3. The thin-film deposition of this material at room temperature and the fabrication of p–n heterojunction diodes on flexible plastic sheets (see Figure) are demonstrated.
