Abstract:
1. A multi-quantum dot device comprising: a channel configured by patterning a top silicon layer of an SOI wafer to have a P-type or intrinsic silicon region formed by connecting a transversal region and a longitudinal region and a plurality of N-type silicon regions formed to have an end point connected to a transversal end of the P-type or intrinsic silicon region; gates including a plurality of tunneling barrier gates, an end of each tunneling barrier gate is positioned on a top of a transversal side of an intersection of the transversal region and the longitudinal region of the P-type or intrinsic silicon region to locally control a potential in the channel; a plurality of coupling gates, an end of each coupling gate is positioned on a top of a point between the intersection and another intersection adjacent to the intersection to locally control the potential in the channel; and a plurality of sensor gates, an end of each sensor gate is positioned on a top of a center of the intersection to sense a state of a quantum dot formed at the intersection; and an inversion layer gate formed on a top of the P-type or intrinsic silicon region to control free electron density.
