Abstract

The electron effective masses for Al_0.15Ga_0.35In_0.5P and Ga_0.5In_0.5P have been investigated using conventional and optically detected cyclotron resonance. For AlGaInP (partly ordered) it is determined to be m*=(0.14±0.01) m₀. For disordered GaInP the mass is found to be m*=(0.092±0.003) m₀ and for ordered material (band gap reduction ∼50 meV) m*=(0.088±0.003) m₀. The experimentally deduced values are compared with those obtained from five‐band k⋅p calculation.
