    摘要:We have proposed an efficient method to quantitatively calculate the band gap values of ternary A(x)B(1-x)C and AB(x)C(1-x) alloyed semiconductors in terms of the dopant concentration x and some fundamental atom parameters such as electronegativity. The calculated band gap values of some typical alloyed semiconductors can agree well with the available experimental data. Taking MgxZn1-xO and CdxZn1-xO as examples, the composition dependent band gap values of alloys with both wurtzite and rocksalt structures were quantitatively predicted. This work provides a guideline in compositionally tuning the band gap of alloyed semiconductors, which will greatly facilitate the band gap engineering of semiconductors.
