Journal ArticleDOI
Enhanced mobility in LaAlO3/SrTiO3 heterostructures with layer-modulated patterning
TL;DR: In this article, two-step deposition in conjunction with layer modulated patterning process can enhance several properties of LaAlO3/SrTiOO3 (LAO/STO) heterostructures grown under a low oxygen partial pressure of 5 x 10−8 Torr.
Book ChapterDOI
Noise in the Single Electron Transistor and its Back Action during Measurement
Göran Johansson,Per Delsing,K. Bladh,David Gunnarsson,Tim Duty,Andreas Käck,Göran Wendin,Abdelhanin Aassime +7 more
TL;DR: In this paper, the authors present a full quantum mechanical calculation of how noise is generated in the SET over the full frequency range, including a new formula for the quantum current noise.

Michael E. Tobar,Eugene Ivanov,Daniel L. Creedon,Jean-Michel Le Floch,Karim Benmessai,Yaohui Fan,Warrick G. Farr,Yarema Reshitnyk,Tim Duty,John M. Martinis +9 more
TL;DR: The Frequency Standards and Metrology Research Group at the University of Western Australia have been developing some of the world's most ultra-precise measurements at microwave frequencies since the 1990s as discussed by the authors.
Journal ArticleDOI
A planar Al-Si Schottky Barrier MOSFET operated at cryogenic temperatures
Wendy E. Purches,Alessandro Rossi,Ruichen Zhao,Sergey Kafanov,Tim Duty,Andrew S. Dzurak,Sven Rogge,Giuseppe C. Tettamanzi +7 more
TL;DR: In this paper, the gate electrode is selfaligned with the device channel and overlaps the source and drain electrodes, which facilitates a sub-5 nm gap between the source/drain and channel, and no spacers are required.
Journal ArticleDOI
Backaction effects of a SSET measuring a qubit spectroscopy and ground State measurement
Benjamin Turek,Johannes Majer,Aashish A. Clerk,Steven Girvin,Andreas Wallraff,K. Bladh,David Gunnarsson,Tim Duty,Per Delsing,Robert Schoelkopf +9 more
TL;DR: In this article, the backaction of a superconducting single-electron transistor (SSET) continuously measuring a Cooper-pair box was investigated and a 2e periodic Coulomb staircase according to the two-level system Hamiltonian was observed.
