    A novel shadow masking technique is proposed for the local variation of growth velocity in GaAs/AlGaAs structures grown on GaAs by metalorganic vapor phase epitaxy. This mask makes use of epitaxially grown spacer and mask layers and windows in the mask are lithographically defined. This results...
