Preparation and Properties of Mg[sub x]Zn[sub 1−x]Te

Abstract

The pseudo‐binary alloy system MgxZn1−xnormalTe has been investigated for 0=x≤0.8 . Compositions containing less than 53 mole per cent (m/o) Mg have a cubic structure with expanded lattice spacings of normalZnTe . For Mg concentrations of 0.53–0.80 m/o the alloys have a hexagonal structure with contracted lattice spacings of normalMgTe . The bandgaps, as determined by electron beam bombardment, vary linearly with composition within the crystalline structure.

Structural Properties of Cd1-xMgxTe and Cd1-x-yMgxMnyTe Crystals

“…To our knowledge, the phase diagram for CdΤe-MgΤe system is still unknown. Our results, however, seem to indicate that considerable segregation of Mg may occur as already reported for ZnTe-MgTe system [3].…”

Phase transition and thermodynamic properties of MgTe under high pressure

“…With the wide-gap binary A N B 8−N semiconductors and promising potential of alkaline earth chalcogenides (AECs) used for various electrical and optical devices, MgTe has recently led to extensive studies in both theoretical [1][2][3][4][5][6][7] and experimental [8,9]. Recently, lots of properties of solids have become possible to compute with great accuracy from the first principles methods.…”

First-principles investigation of wide-gap quaternary alloys Zn1−xMgxSyTe1−y

“…The normal structure of ZnS, ZnTe and MgS is zinc-blende [11], while for MgTe is wurtzite [12]. However, our calculations show that the wurtzite structure of MgTe is only 35.4 meV more stable than zinc-blende structure.…”
