Abstract Single crystals of the two alkali metal zinc oxidotellurates(IV), Rb 2 Zn(TeO 3 )(CO )·H O and Na Zn Te 4 11 , were obtained by reactions mixtures ZnO, TeO CO (molar ratios 2:3:6) 2:3:10), respectively, with small amounts water as a mineralizer. Both compounds crystallize order-disorder (OD) structures layers feature high stacking fault probability. The crystal structure is composed ex...

Basal-plane stacking faults in wurtzite AlN, GaN, and InN are studied using density-functionalpseudopotential calculations. The formation energies follow the trend exhibited for the zinc-blende/wurtzite energy differences in the bulk materials, namely, lowest energy for GaN and highest for AlN. Type-I stacking faults have the lowest energy, followed by type-II stacking faults, and finally extri...
