Ev. Goncharova et al., PHOTOINDUCED REFLECTION OF LIGHT FROM A SINGLE CDTE CDMNTE QUANTUM-WELL WITH A PIEZOELECTRIC INTERNAL FIELD/, JETP letters, 61(11), 1995, pp. 894-899
A photoinduced change in refractive index has been observed and studie
d in strained CdTe/CdMnTe quantum-well heterostructures grown on CdZnT
e substrates in the (111) orientation, The effect stems from a shift o
f resonant frequencies and from a change in the oscillator strengths o
f exciton transitions. It reaches a maximum for exciton transitions be
tween the first electron quantum-well subband and the second hole quan
tum-well subband. (C) 1995 American Institute of Physics.
