Scarpulla, Michael | Enhanced light absorption in thin-film silicon solar cells by scattering from Embedded Dielectric Nanoparticles | We investigate the light-trapping effects of dielectric nanoparticles embedded within the active semiconductor layer of a thin-film solar cell. The baseline model consists of a 1.0 μm slab of crystalline silicon on an aluminum back contact topped with a 75 nm Si3N4 anti-reflective coating. Using fi... | | 2011-01-01 |

Scarpulla, Michael | Enhanced nitrogen incorporation by pulsed laser annealing of GaNxAs1-x formed by N ion implantation | We demonstrate that pulsed laser annealing followed by rapid thermal annealing greatly enhances incorporation of substitutional N in N1-implanted GaAs. Films implanted to 1.8% N exhibit a fundamental band gap of 1.26 eV (a band gap reduction of 160 meV), corresponding to an N activation efficiency ... | Highly mismatched alloys; Gallium arsenide | 2002 |

Tiwari, Ashutosh | Epitaxial growth of ZnO films on Si(111) | In this paper, we report the growth of ZnO films on silicon substrates using a pulsed laser deposition technique. These films were deposited on Si(111) directly as well as by using thin buffer layers of AlN and GaN. All the films were found to have c-axis-preferred orientation aligned with normal to... | Buffer layers; Aluminum nitride; Silicon substrate; Biaxial strain | 2002 |

Mathews, V. John | Equalization of excursion and current-dependent nonlinearities in loudspeakers | This paper presents a novel equalizer for nonlinear distortions in direct-radiator loudspeakers in a closed cabinet by constructing an exact inverse of an electro-mechanical model of the loudspeaker.

Liu, Feng | Equilibrium shape of two-dimensional islands under stress | We show that the equilibrium shape anisotropy of two-dimensional islands in heteroepitaxial growth depends on island size, a consequence of the presence of strain. Even in homoepitaxy, in which the island shape has conventionally been equated with the ratio of step energies, a substrate surface str... | Two-dimensional islands; Equilibrium shape; Heteroepitaxial growth; Homoepitaxy | 2000-08 |

Cohen, Elaine | Error bounded variable distance offset operator for free from curves and surfaces | Most offset approximation algorithms for freeform curves and surfaces may be classified into two main groups. The first approximates the curve using simple primitives such as piecewise arcs and lines and then calculates the (exact) offset operator to this approximation.
