Quaternary alloy Zn 1-x Mg x S y Se 1-y

Abstract: The band-gap energy of II-VI compound semiconductors was simply calculated using a modified dielectric theory. The calculated band-gap energies of MgS and MgSe were 4.62 and 3.67 eV. From the extrapolation of the band-gap energies of ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Mg}}_{x}\mathrm{Se}$ and ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Mg}}_{x}\mathrm{S},$ the band-gap energies of MgSe and MgS of zinc blende at room temperature were determined to be 3.59 and $4.45\ifmmode\pm\else\textpm\fi{}0.2\mathrm{eV},$ almost the same as the value calculated using the modified dielectric theory. The bowing parameter of the ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Mg}}_{x}\mathrm{Se}$ ternary alloy was experimentally obtained as 0 eV, which can be explained in terms of the modified dielectric theory. The lattice constant of the quaternary alloy ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Mg}}_{x}{\mathrm{S}}_{y}{\mathrm{Se}}_{1\ensuremath{-}y}$ can be expressed by Vegard's law [Z. Phys. 5, 17 (1921)]. The band-gap energy of ${\mathrm{Zn}}_{1\ensuremath{-}x}{\mathrm{Mg}}_{x}{\mathrm{S}}_{y}{\mathrm{Se}}_{1\ensuremath{-}y}$ can be expressed by the parabolic function of the composition considering the bowing parameter, where we use of 4.65, 3.59, 3.68, and 2.69 eV as the band-gap energies of MgS, MgSe, ZnS, and ZnSe, respectively.

Plasma system comprising hollow mesh plate electrode

Abstract: A plasma system which eliminates damage derived from charged particles in the plasma and which is able to perform uniform plasma CVD and plasma etching on a large area substrate, wherein a mesh plate having a plurality of holes is placed at the interface of a plasma generation chamber and a substrate treatment chamber which holds a substrate, a high frequency electrical field being applied between an upper electrode in the plasma generation chamber and the mesh plate so as to disassociate the plasma forming gas by electrodischarge so as to cause the generation of plasma. By this, the plasma is isolated from the substrate. On the other hand, source gas supply ports are opened near the holes of the mesh plate, the source gas being introduced from there being brought into contact with the plasma through the holes, whereby the reaction product can be uniformly produced in a broad area. If the reaction product is a deposit-like substance, plasma CVD becomes possible, while if of the etching type, plasma etching becomes possible.
