Simulation of the Pinatubo aerosol cloud in general circulation model

Creator:: Boville, Byron A., Holton, James R., and Mote, Philip W.
Abstract:: A high resolution stratospheric version of the NCAR Community Climate Model (CCM2) with an annual cycle was used to simulate the global transport and dispersion of the Pinatuboa aerosol cloud. A passive tracer was injected into the model stratosphere over the Philippines Islands on model day June15, and the transport...

Improved stability of amorphous zinc tin oxide thin film transistors using molecular passivation

Creator:: Rajachidambaram, M. S., Pandey, A., Vilayurganapathy, S., Nachimuthu, P., Thevuthasan, S., and Herman, G. S.
Abstract:: The role of back channel surface chemistry on amorphous zinc tin oxide (ZTO) bottom gate thin film transistors (TFTs) has been characterized by positive bias-stress measurements and x-ray photoelectron spectroscopy. Positive bias-stress turn-on voltage shifts for ZTO-TFTs were significantly reduced by passivation of back channel surfaces with self-assembled monolayers of...

Defect mechanisms in high resistivity BaTiO₃–Bi(Zn₁/₂Ti₁/₂)O₃ ceramics

Creator:: Raengthon, Natthaphon, DeRose, Victoria J., Brennecka, Geoffrey L., and Cann, David P.
Abstract:: The defect mechanisms that underpin the high energy density dielectric 0.8BaTiO₃–0.2Bi(Zn₁/₂Ti₁/₂) O₃ were investigated. Characterization of the nominally stoichiometric composition revealed the presence of a Ti³⁺-related defect center, which is correlated with lower resistivities and an electrically heterogeneous microstructure. In compositions with 2 mol. % Ba-deficiency, a barium vacancy-oxygen vacancy...

Determination of the Thermal Noise Limit of Graphene Biotransistors

Creator:: Crosser, Michael S., Brown, Morgan A., McEuen, Paul L., and Minot, Ethan D.
Abstract:: 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 imaginary component but has a finite real component. Invoking the fluctuation–dissipation theorem, we determine the power spectral density...

Band alignment at the BaCuSeF/ZnTe interface

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Barati, Alireza, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: 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 conduction-band offset, and a chemically graded interface. By applying the transitivity rule for band offset and on the...

Thermal conductivity of nano-grained SrTiO3 thin films

Creator:: Foley, Brian M., Brown-Shaklee, Harlan J., Duda, John C., Cheaito, Ramez, Gibbons, Brady J., Medlin, Doug, Ihlefeld, Jon F., and Hopkins, Patrick E.
Abstract:: We measure the thermal conductivities of nano-grained strontium titanate (ng-SrTiO₃) films deposited on sapphire substrates via time-domain thermoreflectance. The 170 nm thick oxide films of varying grain-size were prepared from a chemical solution deposition process. We find that the thermal conductivity of ng-SrTiO₃ decreases with decreasing average grain size and attribute...

A two-color twist on test taking

Creator:: Selker, John
Abstract:: Test taking is a humiliating experience for many students, with no perceived direct educational benefit. That need not be so. When circumstances allow, I use a two-pen method of collaborative testing. Students have told me that they leave the exam having figured out what they didn’t understand, filled in the...

Electrical Monitoring of sp³ Defect Formation in Individual Carbon Nanotubes

Creator:: Wilson, Heather, Ripp, Sophie, Prisbrey, Landon, Brown, Morgan A., Sharf, Tal, Myles, Daniel J. T., Blank, Kerstin G., and Minot, Ethan D.
Abstract:: Many carbon nanotube (CNT) applications require precisely controlled chemical functionalization that is minimally disruptive to electrical performance. A promising approach is the generation of sp³ hybridized carbon atoms in the sp²-bonded lattice. We have investigated the possibility of using a carboxylic acid functionalized diazonium reagent to introduce a defined number...

Band-structure, optical properties, and defect physics of the photovoltaic semiconductor SnS

Creator:: Vidal, Julien, Lany, Stephan, d’Avezac, Mayeul, Zunger, Alex, Zakutayev, Andriy, Francis, Jason, and Tate, Janet
Abstract:: 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 minority carrier effective mass as a function of the film orientation. SnS has...

Terahertz imaging of inhomogeneous electrodynamics in single-layer graphene embedded in dielectrics

Creator:: Paul, M. J., Tomaino, J. L., Kevek, J. W., DeBorde, T., Thompson, Z. J., Minot, E. D., and Lee, Yun-Shik
Abstract:: We investigate electron transport properties in large-area, single-layer graphene embedded in dielectric media, using free-space terahertz (THz) imaging and time-domain spectroscopy. Sandwiched between a thin polymethyl methacrylate (PMMA) layer and a Si substrate, graphene layers of different growth recipes exhibit distinctive spatial inhomogeneity of sheet conductivity. The non-contacting, non-destructive THz...
