Zinc oxide light-emitting diodes: a review

3.1. Structure of ZnO. The structure of crystalline ZnO was investigated as far back as in 1935. 6 ZnO crystallizes with the Wurtzite structure (a hexagonal crystal structure, often adopted by binary sulphides and oxides). In this crystalline form zinc ions, Zn 2 + are found on the sites of a hexagonal close packed sublattice interpenetrated by a similar lattice populated with oxygen ions O 2 −.
