  • Zakutayev, Andriy; Tate, Janet; Platt, Heather A. S.; Keszler, Douglas A.; Barati, Alireza; Klein, Andreas; Jaegermann, Wolfram (American Institute of Physics, 2010-04-19)
    In situ photoemission spectroscopy experiments are used to characterize the interface between ZnTe and the wide band gap p-type semiconductor BaCuSeF. The contact is characterized by a null valence-band offset, a large c ...
  • Vidal, Julien; Lany, Stephan; d’Avezac, Mayeul; Zunger, Alex; Zakutayev, Andriy; Francis, Jason; Tate, Janet (American Institute of Physics, 2012-01-16)
    SnS is a potential earth-abundant photovoltaic (PV) material. Employing both theory and experiment to assess the PV relevant properties of SnS, we clarify on whether SnS has an indirect or direct band gap and what is the ...
  • Chien, Chih-Chun; Zwolak, Michael; Di Ventra, Massimiliano (American Physical Society, 2012-04-10)
    Using the microcanonical picture of transport-a framework ideally suited to describe the dynamics of closed quantum systems such as ultracold atom experiments-we show that the exact dynamics of noninteracting fermions an ...
  • Johnson, Brian; Kendrick, Mark J.; Ostroverkhova, Oksana (American Institute of Physics, 2013-09-04)
    We present a model that describes nanosecond (ns) time-scale photocurrent dynamics in functionalized anthradithiophene (ADT) films and ADT-based donor-acceptor (D/A) composites. By fitting numerically simulated photocurr ...
  • Eberly, B.; Aliaga, L.; Altinok, O.; Schellman, H.; et al. (American Physical Society, 2015-11-23)
    Charged pion production via charged-current nu[subscript]μ interactions on plastic scintillator (CH) is studied using the MINERvA detector exposed to the NuMI wideband neutrino beam at Fermilab. Events with hadronic inva ...
  • Hughes, Jessica; Krebs, Eric J.; Roundy, David (American Institute of Physics, 2013-01-14)
    We develop a classical density functional for water which combines the White Bear fundamental-measure theory (FMT) functional for the hard sphere fluid with attractive interactions based on the statistical associating fl ...
  • Sun, Bo (Institute of Physics, Chinese Academy of Sciences, Chinese Physical Society, 2015-03-05)
    English Abstract:Mechanical interaction between cancer cells and their microenvironment plays a central role in the progression of tumors. In vitro models based on biopolymer networks have been successfully employed to s ...
  • Bernardini, M. G.; Ghirlanda, G.; Campana, S.; Lazzati, D.; et al. (Oxford University Press, 2015-01-11)
    We investigated the rest frame spectral lags of two complete samples of bright long (50) and short (6) gamma-ray bursts (GRB) detected by Swift. We analysed the Swift/BAT data through a discrete cross-correlation funct ...
  • Zwolak, Michael; Zurek, Wojciech H. (Nature Publishing Group, 2013-05-20)
    The sum of the Holevo quantity (that bounds the capacity of quantum channels to transmit classical information about an observable) and the quantum discord (a measure of the quantumness of correlations of that observable ...
  • Velizhanin, Kirill A.; Sahu, Subin; Chien, Chih-Chun; Dubi, Yonatan; Zwolak, Michael (Nature Publishing Group, 2015-12-04)
    Kramers’ theory frames chemical reaction rates in solution as reactants overcoming a barrier in the presence of friction and noise. For weak coupling to the solution, the reaction rate is limited by the rate at which the ...
  • Foster, D. H.; Barras, F. L.; Vielma, J. M.; Schneider, G. (American Physical Society, 2013-11-08)
    The p-type semiconductor Cu₃PSe₄ has recently been established to have a direct band gap of 1.4 eV and an optical absorption spectrum similar to GaAs [Foster et al., Appl. Phys. Lett. 99, 181903 (2011)], suggesting a p ...
  • Zakutayev, A.; Tate, J.; Schneider, G. (The American Physical Society, 2010-11-15)
    Native point defects, defect complexes, and oxygen impurities in BaCuChF were studied using density functional theory calculations, self-consistent thermodynamic simulations, and various experimental techniques. Uninte ...
  • Rajesh, Kallarakkal Ramakrishnan; Paudel, Keshab; Johnson, Brian; Hallani, Rawad; Anthony, John; Ostroverkhova, Oksana (Society of Photo-Optical Instrumentation Engineers, 2015-01-09)
    We explored relationships between photophysical processes and solar cell characteristics in solution-processable bulk heterojunctions (BHJs), in particular: (1) polymer donor:fullerene acceptor:small-molecule (SM) nonf ...
  • Crosser, Michael S.; Brown, Morgan A.; McEuen, Paul L.; Minot, Ethan D. (American Chemical Society, 2015-08)
    To determine the thermal noise limit of graphene biotransistors, we have measured the complex impedance between the basal plane of single-layer graphene and an aqueous electrolyte. The impedance is dominated by an imagin ...
  • Liu, Weimin; Wang, Liang; Han, Fangyuan; Fang, Chong (Optical Society of America, 2013-09-01)
    We achieve a series of distinct broadband third-harmonic generation (THG) signals at the amorphous glass–air interface attributed to third-order and cascaded third-order nonlinear processes. A novel THG laser sideband a ...
  • Margutti, R.; Guidorzi, C.; Lazzati, D.; et al. (IOP Publishing, 2015-06-01)

  • Ajith, P.; Fotopoulos, N.; Privitera, S.; Neunzert, A.; Mazumder, N.; Weinstein, A. J. (American Physical Society, 2014-04-08)
    We report the construction of a three-dimensional template bank for the search for gravitational waves from inspiralling binaries consisting of spinning compact objects. The parameter space consists of two dimensions d ...
  • Hoffman, R. L.; Wager, J. F.; Jayaraj, M. K.; Tate, J. (American Institute of Physics, 2001-12-01)
    Transparent p – i – n heterojunction diodes are fabricated using heavily doped, p-type CuYO₂ and semi-insulating i-ZnO thin films deposited onto a glass substrate coated with n-type indium tin oxide. Rectification is o ...
