  • Epitaxial growth of Cu on Cu(001): Experiments and simulations 

    Furman, Itay; Biham, Ofer; Zuo, Jiang-Kai; Swan, Anna K.; Wendelken, John F. (American Physical Society (APS), 2000-10-15)
    A quantitative comparison between experimental and Monte Carlo simulation results for the epitaxial growth of Cu/Cu(001) in the submonolayer regime is presented. The simulations take into account a complete set of hopping ...
  • Chirality dependence of the radial breathing phonon mode density in single wall carbon nanotubes 

    Vamivakas, A. N.; Yin, Y.; Walsh, A. G.; Unlu, M. S.; Goldberg, B. B.; Swan, A. K. (2006-09-01)
    A mass and spring model is used to calculate the phonon mode dispersion for single wall carbon nanotubes (SWNTs) of arbitrary chirality. The calculated dispersions are used to determine the chirality dependence of the ...
  • 2D Raman band splitting in graphene: charge screening and lifting of the K-point Kohn anomaly 

    Wang, Xuanye; Christopher, Jason W.; Swan, Anna K. (NATURE PUBLISHING GROUP, 2017-10-19)
    Pristine graphene encapsulated in hexagonal boron nitride has transport properties rivalling suspended graphene, while being protected from contamination and mechanical damage. For high quality devices, it is important to ...
  • Mems device with large out-of-plane actuation and low-resistance interconnect and methods of use 

    Holyoak, Michael Jarret; Kannell, George Kenneth; Beacken, Marc Jay; Bishop, David J.; Chang, Jackson; Imboden, Matthias (2017-05-18)
    The present application is directed to a MEMS device. The MEMS device includes a substrate having a first end and a second end extending along a longitudinal axis, the Substrate including an electrostatic actuator. The ...
  • Standardizing design performance comparison in microfluidic manufacturing 

    Sanka, Radhakrishna; Crites, Brian; Lippai, Joshua; McDaniel, Jeffery; Brisk, Philip; Densmore, Douglas (IWBDA 2018, 2018-08)
    Microfluidic devices published in literature today lack sufficient information for automating the physical design process. Moreover, the constantly changing landscape of manufacturing and technological requirements poses ...
  • A reverse predictive model towards design automation of microfluidic droplet generators 

    Lashkaripour, Ali; Rodriguez, Christopher; Douglas, Densmore (International Workshop on Bio-Design Automation (IWBDA), 2018-08-03)
    Droplet-based microfluidic devices in comparison to test tubes can reduce reaction volumes 10^9 times and more due to the encapsulation of reactions in micro-scale droplets [4]. This volume reduction, alongside higher ...
  • Response of convection electric fields in the magnetosphere to IMF orientation change 

    Nishimura, Y.; Kikuchi, T.; Wygant, J.; Shinbori, A.; Ono, T.; Matsuoka, A.; Nagatsuma, T.; Brautigam, D. (2009)
    [1] The transient response of convection electric fields in the inner magnetosphere to southward turning of the interplanetary magnetic field (IMF) is investigated using in‐situ electric field observations by the CRRES and ...
  • User-profile-based analytics for detecting cloud security breaches 

    Tiwari, Trishita; Turk, Ata; Oprea, Alina; Olcoz, Katzalin; Coskun, Ayse K. (IEEE, 2017-01-01)
    While the growth of cloud-based technologies has benefited the society tremendously, it has also increased the surface area for cyber attacks. Given that cloud services are prevalent today, it is critical to devise systems ...
  • On the topological characterization of near force-free magnetic fields, and the work of late-onset visually-impaired topologists 

    Kotiuga, P. Robert (AMER INST MATHEMATICAL SCIENCES-AIMS, 2016-02-01)
    The Giroux correspondence and the notion of a near force-free magnetic field are used to topologically characterize near force-free magnetic fields which describe a variety of physical processes, including plasma equilibrium. ...
  • Self-adjoint curl operators 

    Hiptmair, Ralf; Kotiuga, Peter Robert; Tordeux, Sebastien (Springer, 2012-09-01)
    We study the exterior derivative as a symmetric unbounded operator on square integrable 1-forms on a 3D bounded domain D. We aim to identify boundary conditions that render this operator self-adjoint. By the symplectic ...
