Journal ArticleDOI
Atomically precise placement of single dopants in si.
Steven R. Schofield,Neil J. Curson,Michelle Y. Simmons,F.J. Ruess,Toby Hallam,L. Oberbeck,R. G. Clark +6 more
TL;DR: It is shown that it is possible to thermally incorporate P atoms into Si(001) below the H-desorption temperature and control over the precise spatial location at which P atoms are incorporated was achieved using STM H lithography.
Journal ArticleDOI
Charge-based quantum computing using single donors in semiconductors
Lloyd C. L. Hollenberg,Andrew S. Dzurak,Cameron J. Wellard,Alex R. Hamilton,David J. Reilly,Gerard J. Milburn,R. G. Clark +6 more
TL;DR: In this paper, a charge qubit consisting of two dopant atoms in a semiconductor crystal, one of which is singly ionized, was used to encode a single-atom quantum computer.
Journal ArticleDOI
Gate-defined quantum dots in intrinsic silicon.
TL;DR: It is demonstrated that depletion gates are an effective technique for defining quantum dots in silicon with tunable tunnel barriers in a narrow-channel field-effect transistor.
Journal ArticleDOI
Controlled shallow single ion implantation in silicon using an active substrate for sub-20 keV ions
David N. Jamieson,C. Yang,T. Hopf,S.M. Hearne,Christopher Ian Pakes,Steven Prawer,M. Mitic,E. Gauja,Søren Andresen,Fay E. Hudson,Andrew S. Dzurak,R. G. Clark +11 more
TL;DR: In this paper, the authors demonstrate a method for the controlled implantation of single ions into a silicon substrate with energy of sub-20kV. The method is based on the collection of electron-hole pairs generated in the substrate by the impact of a single ion.
Journal ArticleDOI
Towards the fabrication of phosphorus qubits for a silicon quantum computer
Jeremy L. O'Brien,Steven R. Schofield,Michelle Y. Simmons,R. G. Clark,Andrew S. Dzurak,Neil J. Curson,Bruce E. Kane,N. S. McAlpine,Marilyn E. Hawley,Geoff W. Brown +9 more
TL;DR: In this article, it is shown that it is possible to fabricate an atomically precise linear array of single phosphorus bearing molecules on a silicon surface with the required dimensions for the fabrication of a silicon-based quantum computer.
