Abstract
For the first time, a general viewpoint of electronegativity and chemical bond in alloy semiconductors, e.g., Mg x Zn 1-x O (x = 0.0-1.0) was proposed. The variation of bulk modulus and bond length, as well as their dependence on Mg concentration x were quantitatively simulated. The bulk moduli of Mg x Zn 1-x O alloys decrease with increasing Mg concentration x. The detailed variation of bond lengths of both Mg–O and Zn–O in Mg x Zn 1-x O alloys in the whole composition range was determined, which is less than 0.007 Å. The valence state of Mg is larger than that of Zn when x = 0.0-1.0, which leads to the increase of valence state of O with increasing Mg concentration x. The current results clearly indicate that Mg x Zn 1-x O condenses in an alloy state.
