Abstract
Hall mobility measurements for the alloy III–V quaternary material In1-x}Gax}Asy}P1-y} lattice matched to semi-insulating InP substrates are described. For samples spanning the entire compositional range, the carrier concentration varied from 0.4x1016} to 1017}cm−3 and the room temperature mobilities varied from 3800cm2}/Vsec up to 11,000cm2}/Vsec. Temperature variation of the mobility in the range from 80K to 300K was investigated for selected samples. The results demonstrate that disorder scattering makes a significant contribution to limiting the mobility for material spanning the midrange (y∼0.5).
