Transparent p-type conducting BaCu₂S₂ films

Creator:: Park, Sangmoon, Keszler, Douglas A., Valencia, Melinda M., Hoffman, Randy L., Bender, Jeffrey P., and Wager, John F.
Abstract:: p-type conducting films of α- BaCu₂S₂ have been deposited onto glass and KBr substrates, yielding a conductivity of 17 S/cm and a Hall mobility of 3.5 cm²/Vs. For a 430-nm-thick film, the optical transparency approaches 90% in the visible portion of the spectrum at 650 nm, and a transparency of...

Mechanical stability of ultrathin Ge/Si film on SiO2: The effect of Si/SiO2 interface

Creator:: Huang, Minghuang, Nairn, John A., Liu, Feng, and Lagally, M. G.
Abstract:: We perform two-dimensional linear elastic finite element analysis to investigate the mechanical stability of ultrathin Ge/Si film grown on or bonded to SiO₂, using imperfect interface elements between Si and SiO₂ to model Si/SiO₂ interfacial slippage. We demonstrate that the overall composite film is stable when only the tangential slippage...

Dielectric and polarization experiments in high loss dielectrics: A word of caution

Creator:: Maglione, M. and Subramanian, M. A.
Abstract:: The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state. In this report, we call for caution when samples are simultaneously displaying an insulating behavior and a...

Effects of ZrO₂ additions on the dielectric properties of CaCu₃Ti₄O₁₂

Creator:: Patterson, Eric A., Kwon, Seunghwa, Huang, Chien-Chih, and Cann, David P.
Abstract:: The dielectric spectra of CaCu₃Ti₄O₁₂ is characterized by a large permittivity (εᵣ>10 000) with only a weak dependence on temperature over the temperature range 200–400 K. In this work, doping with 0.1–1.0 wt % ZrO₂ has been shown to dramatically reduce the dielectric loss. At 0.5 wt % ZrO₂, tan...

Room temperature multiferroic properties of single-phase (Bi₀.₉La₀.₁)FeO₃-Ba(Fe₀.₅Nb₀.₅)O₃ solid solution ceramics

Creator:: Paik, Hanjong, Hwang, Hosung, No, Kwangsoo, Kwon, Seunghwa, and Cann, David P.
Abstract:: The crystal structure and multiferroic properties of single-phase (Bi₀.₉La₀.₁)FeO₃–Ba(Fe₀.₅Nb₀.₅)O₃ ceramics were investigated. The rhombohedral-type structure of 1.0(Bi₀.₉La₀.₁)FeO₃) was transformed to a monoclinic-type structure for the 0.5(Bi₀.₉La₀.₁)FeO₃–0.5Ba(Fe₀.₅Nb₀.₅)O₃) composition. It shows the coexistence of ferroelectricity and magnetism at room temperature, represented by a high dielectric constant with ferroelectric hysteresis and clear magnetic...

Quantification of free volume differences in a Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅ bulk amorphous alloy

Creator:: Launey, M. E., Kruzic, J. J., Li, C., and Busch, R.
Abstract:: Deformation of metallic glasses requires the existence of free volume to allow atomic movement under mechanical loading. Accordingly, quantification of the free volume state of the alloy is crucial to understand it's mechanical behavior. By annealing below the glass transition temperature, the free volume of a Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅ bulk metallic glass...

Generation of terahertz pulses with arbitrary elliptical polarization

Creator:: Amer, N., Hurlbut, Walter C., Norton, B. J., Lee, Yun-Shik, and Norris, T. B.
Abstract:: We employ two different methods to generate controllable elliptical polarization of teraherz (THz) pulses. First, THz pulses are generated via optical rectification in nonlinear crystals using a pair of temporally separated and perpendicularly polarized optical pulses. The THz ellipticity is controlled by adjusting the relative time delay and polarization of...

Terahertz pulse shaping via optical rectification in poled lithium niobate

Creator:: Lee, Yun-Shik, Amer, N., and Hurlbut, Walter C.
Abstract:: We demonstrate a technique for terahertz pulse shaping via optical rectification in the pre-engineered domain structure of poled lithium niobate crystals. The terahertz wave forms coincide with the crystal domain structures. The one-dimensional nonlinear wave equation simulates the experimental results with a good qualitative agreement.

Terahertz-wave generation in quasi-phase-matched GaAs

Creator:: Vodopyanov, K. L., Fejer, M. M., Yu, X., Harris, J. S., Lee, Yun-Shik, Hurlbut, Walter C., Kozlov, V. G., Bliss, D., and Lynch, C.
Abstract:: The authors demonstrate an efficient room temperature source of terahertz radiation using femtosecond laser pulses as a pump and GaAs structures with periodically inverted crystalline orientation, such as diffusion-bonded stacked GaAs and epitaxially grown orientation-patterned GaAs, as a nonlinear optical medium. By changing the GaAs orientation-reversal period (504–1277 μm), or...
