H. Akiyama et al., PHOTOLUMINESCENCE STUDY OF LATERAL CONFINEMENT ENERGY IN T-SHAPED INXGA1-XAS QUANTUM WIRES, Physical review. B, Condensed matter, 57(7), 1998, pp. 3765-3768
A study of high-quality InxGa1-xAs T-shaped quantum wires (T-QWR's) vi
a photoluminescence spectroscopy to characterize the lateral confineme
nt effect is reported. The effective lateral confinement energy of exc
itons in 3.5-nm-scale In0.17Ga0.83As/Al0.3Ga0.7As T-QWR's is found to
be as large as 34 meV. The value has been examined in comparison with
the previous results on GaAs/Al0.3Ga0.7As and GaAs/AlAs T-QWR's. [S016
