Electrical Properties of ZnO Single Crystals

The electrical parameters, especially the conductivity, were investigated early in history of ZnO research. An overwiew over electronic properties of ZnO up to the end of the 1950s was given by Heiland et al. in 1959 [7]. Most of the early investigations up to about 1955 were performed on sintered polycrystalline ZnO samples [4,8], which suffered from the general problem of conduction in porous, inhomogeneous materials with a lower density compared with 

All samples show the typical behavior of a semiconductor, i.e., decreasing conductivity with decreasing temperature. The different sample groups
