Abstract(in Japanese) (See Japanese page)
Abstract(in English) We fabricated single electron devices by using selective area MOVPE and investigated their transport properties.GaAs/AlGaAs modulation doped heterostructures are grown on a GaAs(001)substrate partially masked with SiNx and narrow channel surrounded by facet sidewalls are formed near the top.The width of the channel is modulated by an appropriate patterning of the mask.By applying negative biases to a gate, a quantum dot connected with quantum wires through tunnel barriers are formed near the pinch-off voltage, as a result of the expansion of depletion layers.We successfully observed clear Coulomb blockade oscillations at low temperatures.We also fabricate logic circuits with an SET and a variable load resistance, and confirmed inverter operations.
