Abstract :
Summary form only given. The size effects in nonlinear optical response of amorphous Si-SO/sub 2/ MQW are studied by second-harmonic generation (SHG) spectroscopy. The sensitivity of the SHG spectroscopy to electronic structure (subband energy position and density of states lineshapes) of MQW down to sub-nanoscale of the well thicknesses is demonstrated.
