Crystal Structure of Wurtzite. Zinc sulfide crystallizes in two different forms: wurtzite and zinc blende. The ionic radius of the zinc(II) ion is 0.74 Å and that of the sulfide ion is 1.70 Å. The ratio of radii for the cation and anion is thus r + /r-= 0.74/1.70 = 0.44.

The wurtzite group includes cadmoselite (CdSe), greenockite (CdS), mátraite (ZnS), and rambergite (MnS), in addition to wurtzite. Its crystal structure is called the wurtzite crystal structure, to which it lends its name. This structure is a member of the hexagonal crystal system and consists of tetrahedrally coordinated zinc and sulfur atoms Crystal Structure of Wurtzite. Zinc sulfide crystallizes in two different forms: Wurtzite and Zinc Blende. The ionic radius of the zinc(II) ion is 0.74 angstroms and that of the sulfide ion is 1.70 angstroms.
Can antimonide-based nanowires form wurtzite crystal structure? Gorji, Sepideh LU; Lehmann, Sebastian LU and Dick Thelander, Kimberly LU () In Nanoscale 8 (5). p.2778-2786. Mark; Abstract The epitaxial growth of antimonide-based nanowires has become an attractive subject due to their interesting properties required for various applications such as long-wavelength IR detectors.

Among the compounds that can take the wurtzite structure are wurtzite itself (ZnS or ZnS with up to 8% iron instead of zinc), AgI, ZnO, CdS, CdSe, α-SiC, GaN, AlN, w-BN and other semiconductors. The wurtzite crystal structure, named after the mineral wurtzite, is a crystal structure for various binary compounds.

However, their crystal structure changes when they form MnS 1−x Se x alloys at lower temperatures within this range. At 420 °C, the MnS 1− x Se x alloys have the RS structure across the entire composition range, the same as the end-member compound, and similar to other isostructural alloys (e.g., WZ Al x Ga 1− x N [ Reference Morko 17 ] or ZB CdTe 1− x Se x ) [ Reference Böer 18 ].

For wurtzite crystal structure the surfaces of equal energy in Γ valley should be ellipsoids, but effective masses in z direction and perpendicular directions are estimated to be approximately the same:
