摘要: This invention concerns an electronic device for the control and readout of the electron or hole spin of a single dopant in silicon. The device comprises a silicon substrate in which there are one or more ohmic contact regions. An insulating region on top of the substrate. First and second barrier gates spaced apart to isolate a small region of charges to form an island of a Single Electron Transistor (SET). A third gate over-lying both the first and second barrier gates, but insulated from them, the third gate being able to generate a gate-induced charge layer (GICL) in the ESR line substrate beneath it. A fourth gate in close proximity to a single dopant donor gate atom, the dopant atom being encapsulated in the substrate outside the region of the GICL but close enough to allow spin-dependent charge tunnelling between the dopant atom and the SET island under the control of gate potentials, mainly the fourth gate. In use either the third or fourth gate also serve as an Electron Spin Resonance (ESR) line to control the spin of the single electron or hole of the dopant atom. In a further aspect it concerns a method for using the device.

摘要: This invention concerns nanoscale products, such as electronic devices fabricated to nanometer accuracy. It also concerns atomic scale products. These products may have an array of electrically active dopant atoms in a silicon surface, or an encapsulated layer of electrically active donor atoms. In a further aspect the invention concerns a method of fabricating such products. The methods include forming a preselected array of donor atoms incorporated into silicon. Encapsulation by growing silicon over a doped surface, after desorbing the passivating hydrogen. Also, using an STM to view donor atoms on the silicon surface during fabrication of a nanoscale device, and measuring the electrical activity of the donor atoms during fabrication of a nanoscale device. Such products and processes are useful in the fabrication of a quantum computer, but could have many other uses.
