Strain Status

AbstractThe strain status of the buried InAs self-assembled quantum dot was comprehended by measurement first time. Results show the in-plane strain is compressive and lattice in the growth direction is lager than the lattice of GaAs. The strain of the sample annealed at 650 degree relaxes in the growth direction. The growth and the lateral direction become relaxed in the sample annealed at 750 degree.

ABSTRACTWe have fabricated and characterized the lateral electron transport through InAs quantum dots with double barrier system. Aluminum metal electrodes with the inter-electrode spacing of 30 nm have been deposited on an InAs self-assembled quantum dot wafer to form the planar type quantum dot devices. Current peak structure and negative differential resistance effects are observed above 77 K in current-voltage characteristics. These results are interpreted as due to 3D-0D resonant tunneling through the single quantum dot positioned in between the electrodes.
