Wurtzite definition, a dimorph of sphalerite, zinc sulfide, ZnS, similar in structure to greenockite and brownish-black in color. See more.
2021-03-03 · The variety of wurtzite-type semiconductors with band gaps of 1.8–2.5 eV is limited, which hinders filling the “green gap”. This remains an unresolved problem in green light-emitting diodes (LEDs). Wurtzite-type MgSnN2 is a ternary nitride with a band gap of ∼2 eV, and studying it as a potential candidate for green emitters in LEDs and an absorber material in tandem photovoltaics has Name: Wurtzite RRUFF ID: R060181 Ideal Chemistry: ZnS Locality: Silver Islet mine, Thunder Bay, Ontario, Canada Source: Lloyd Twaites Owner: RRUFF Description: Dark-brown hexagonal prisms, polytype 2H Status: The identification of this mineral is confirmed by single-crystal X-ray diffraction and chemical analysis.

Wurtzite definition is - a brownish black mineral ZnS that consists of zinc sulfide in hemimorphic hexagonal crystals or a fibrous state and that is polymorphous with sphalerite. ZnS – Wurtzite: Interactive 3D Structure.
Point Group: 6mm. Crystals to 1.5 cm, commonly hemimorphic pyramidal {5052} and {1011}; also short prismatic to tabular {0001}; typically striated GaN, Wurtzite.
