  • Bawendi, Moungi G.; Geyer, Scott Mitchell; Porter, Venda J.; Halpert, Jonathan E.; Mentzel, Tamar; Kastner, Marc (American Physical Society, 2010-10)
    We report the influence of trap states on charge transport through films of mixed CdTe and CdSe nanocrystals (NCs) between lateral electrodes, through layered films of CdTe and CdSe NCs in a layered geometry, and through ...
  • Mentzel, Tamar; MacLean, Kenneth; Kastner, Marc (American Chemical Society (ACS), 2011-09)
    Contact effects are a common impediment to electrical measurements throughout the fields of nanoelectronics, organic electronics, and the emerging field of graphene electronics. We demonstrate a novel method of measuring ...
  • MacLean, Kenneth; Mentzel, Tamar; Kastner, Marc (American Chemical Society, 2010-12)
    We investigate the effect of electrostatic screening on a nanoscale silicon MOSFET electrometer. We find that screening by the lightly doped p-type substrate, on which the MOSFET is fabricated, significantly affects the ...
  • Lin, Xi; Hu, Jingshi; Lai, Andrew Pan; Zhang, Zhenning; MacLean, Kenneth; Dillard, Colin R.; Xie, Ya-Hong; Kastner, Marc (American Institute of Physics (AIP), 2011-07)
    Quantum dots in Si/SiGe heterostructures are expected to have relatively long electron spin decoherence times, because of the low density of nuclear spins and the weak coupling between nuclear and electron spins. We provide ...
  • Ray, Nirat; Hanson, Micah P.; Gossard, Arthur C.; Staley, Neal Edward; Kastner, Marc (American Physical Society, 2014-11)
    We investigate electron transport through a finite two dimensional mesoscopic periodic potential, consisting of an array of lateral quantum dots with electron density controlled by a global top gate. We observe a transition ...
  • Lin, X.; Dillard, Colin R.; Kastner, Marc; Pfeiffer, L. N.; West, K. W. (American Physical Society, 2012-04)
    Some models of the 5/2 fractional quantum Hall state predict that the quasiparticles, which carry the charge, have non-Abelian statistics: exchange of two quasiparticles changes the wave function more dramatically than ...
  • MacLean, Kenneth; Mentzel, Tamar; Kastner, Marc (American Chemical Society, 2010-03)
    We measure charge transport in a hydrogenated amorphous silicon (a-Si:H) thin film using a nanometer scale silicon MOSFET as a charge sensor. This charge detection technique makes possible the measurement of extremely large ...
  • Mentzel, Tamar; Wanger, Darcy Deborah; Ray, Nirat; Walker, Brian J.; Strasfeld, David B.; Bawendi, Moungi G.; Kastner, Marc (American Chemical Society, 2012-07)
    We present the first semiconductor nanocrystal films of nanoscale dimensions that are electrically conductive and crack-free. These films make it possible to study the electrical properties intrinsic to the nanocrystals ...
