Optical Property Characterization of Silicon Quantum Wires
Keyword(s):
ABSTRACTThe recent success of bulk synthesis of pure nano-scale silicon quantum wires (SiQW's) enables us to evaluate their photoluminescence (PL) characteristics under ultra-violet photoexcitation. Intense multiple light emissions ranging from dark red to blue regions were revealed for as-grown and partially oxidized SiQW samples. The physical origin of the multiemissions is discussed on the basis of quantum confinements, or defect centers.
