Quantization effects that arise from the confinement of charge carriers in semiconductors with potential wells of small dimensions have been extensively studied in recent years. The vast bulk of the work to date has been done in thin-film, laminar structures. These structures are one-dimensional quantum wells; when multiple wells are electronically coupled the resulting layered structures are termed superlattices. Quantum confinement in two dimensions results in quantum well wires, and such systems have recently been reported. Quantum confinement in three dimensions should occur with small semiconductor particles. The authors report initial experiments with small colloidal particles of CdS and PbS that show optical effects due to quantization in three dimensions.
