Calculational method for isoparametric compositions and the width of the forbidden band of five-component solid solutions based on AIII BV compounds

Quinary InAlGaPAs/GaAs solid solutions grown by temperature gradient zone melting

“…For calculate the lattice constant a(x, y, z), and the bandgap (Eg) using equation from [10]. The InxAlyGa1-x-yPzAs1-z/GaAs heterostructures even with a slight increase concentration of indium (x) isoperiodic line shifted to the region of high phosphorus concentrations ( figure 1).…”

“…V compounds enable to independently modify the lattice constant, the bandgap and the coefficient of thermal expansion (CTE) [1]. This create opportunities for obtaining isoparametric (izoperiodic and CTE matched) heterostructures based on the binary compounds and working in a wider spectral range than quaternary solid solution [2].…”
