(color online) Composition-dependent band gap and lattice constant relationship of quaternary Al_zGa_xIn_yAs system. Solid lines show contours of band gap energy in unit eV, dashed lines denote the contours of lattice constants in unit Å, and three axes represent the ternaries of Al_{1 − x}Ga_xAs, In_yGa_{1 − y}As, and In_{1 − z}Al_zAs respectively. The shadow region refers to indirect band zone.
