摘要：
A series of (Ga, In)As/GaAs/Ga(As, Sb) multi-quantum well heterostructures is analyzed using temperature-and power-dependent photoluminescence (PL) spectroscopy. Pronounced PL variations with sample temperature are observed and analyzed using microscopic many-body theory and band structure calculations based on the k.p method. This theory-experiment comparison reveals an unusual, temperature dependent variation of the band alignment between the (Ga, In) As and Ga(As, Sb) quantum wells. Published by AIP Publishing.
