  • A quantitative study of bias triangles presented in chemical potential space 
    Perron, Justin; Stewart, M. D.; Zimmerman, Neil (Journal of Physics: Condensed Matter, 2015-05-20)
    We present measurements of bias triangles in several biasing configurations. Using a capacitive model and two fit parameters we are able to predict the shapes and locations of the bias triangles in all measurement ...
  • Long-distance correlation-length effects and hydrodynamics of 4He films in a Corbino geometry 
    Thomson, Stephen; Perron, Justin; Gasparini, Francis (Physical Review B, 2016-09-26)
    Previous measurements of the superfluid density ρs and specific heat for 4He have identified effects that are manifest at distances much larger than the correlation length ξ3D [1–3]. We report here new measurements of the ...
  • A new regime of Pauli-spin blockade 
    Perron, Justin; Stewart, M.D.; Zimmerman, Neil (Journal of Applied Physics, 2016-04-07)
    Pauli-spin blockade (PSB) is a transport phenomenon in double quantum dots that allows for a type of spin to charge conversion often used to probe fundamental physics such as spin relaxation and singlet-triplet coupling. ...
  • Valley blockade in a silicon double quantum dot 
    Perron, Justin; Gullans, Michael; Taylor, Jacob; Stewart, M.D.; Zimmerman, Neil (Physical Review B, 2017-11-13)
    Electrical transport in double quantum dots (DQDs) illuminates many interesting features of the dots' carrier states. Recent advances in silicon quantum information technologies have renewed interest in the valley states ...
  • AC signal characterization for optimization of a CMOS single-electron pump 
    Murray, Roy; Perron, Justin; Stewart, M D; Zimmerman, Neil (Nanotechnology, 2018-01-08)
    Pumping single electrons at a set rate is being widely pursued as an electrical current standard. Semiconductor charge pumps have been pursued in a variety of modes, including single gate ratchet, a variety of 2-gate ratchet ...
