Nanometer-sized features as small as 400Åhave been fabricated in single-quantum-well GaAs/A1GaAs heterostructures for studies of quantum confinement effects in quantum dots. The features have been fabricated by dry-etching techniques using nanometer-sized etch masks by a novel surface deposition of colloidally-suspended spherical particles. SEM was used to examine the feature size.
