Zinc-blende — wurtzite polytypism in semiconductors Chin-Yu Yeh, Z. W. Lu, S.Froyen, and Alex Zunger National Renewable Energy Laboratory, Golden, Colorado 80401 (Received 16July 1992} The zinc-blende (ZB) and wurtzite (W) structures are the most common crystal forms of binary octet semiconductors.

To recap, zincblende is best thought of as a face-centered cubic array of anions cations occupying one half of the tetrahedral holes. Each ion is 4-coordinate and has local tetrahedral geometry. Unlike wurtzite, zincblende is its own antitype -- you can switch the anion and cation positions in the cell and it doesn't matter (as in NaCl).

NaCl cluster model consists of 125 unit cells. Exploring the interior of Most of the thesis is devoted to the study of (110) surfaces. This surface is the natural cleavage plane for zincblende semiconductor compounds and is thus The band offset between wurtzite (wz) and zinc-blende (zb) GaAs is an important fundamental parameter in polytype heterostructure engineering.

Indeed, while polytypism between a wurtzite and a zinc blende phase is often seen in some II-VI compounds, it has only rarely been observed in ZnO. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [ (ZnFe)S], and a zinc carbonate known as calamine or smithsonite (ZnCO 3). Miners have also been known to refer to sphalerite as zinc blende, black jack and ruby jack. The mineral crystallizes in the cubic crystal system.

Zn2+ is bonded to four equivalent S2- atoms to form corner-sharing ZnS4 tetrahedra.
