摘要
We have observed the population of the second two-dimensional electron subband in δ-doped Al0.48In0.52As/Ga0.47In0.53As heterostructures by Shubnikov-de Haas measurements. After illuminating the samples at low temperature, the electron density increases from 17.3 to 18.2×1011 cm-2 for the first subband and from 3.6 to 4.1×1011 cm-2 for the second subband. The population of the second subband begins when the first subband is filled at a density of 10.3×1011 cm-2. The effective mass of the second subband is equal to (0.045±0.003)m0, indicating significant band nonparabolicity in the Ga0.47In0.53As well.© 1995 American Institute of Physics.
