| 英文摘要 | Elastic constants, the bulk modulus, young's modulus, band-gap bowing coefficients, spontaneous and piezoelectric polarizations, and piezoelectric coefficients of hexagonal al(x)ga(1-x)n ternary alloys are calculated using first-principles methods. the fully relaxed structures and the structures subjected to homogeneous biaxial and uniaxial tension are investigated. we show that the biaxial tension in the plane perpendicular to the c axis and the uniaxial tension along the c axis all reduce the bulk modulus, whereas they reduce and enhance young's modulus, respectively. we find that the biaxial and uniaxial tension can enhance the bowing coefficients. we also find that the biaxial tension can enhance the total polarization, while the uniaxial tension will suppress the total polarization.
