Effects of Solution pH and Surface Chemistry on the Post-Deposition Growth of Chemical Bath Deposited PbSe Nanocrystalline Films

October 12, 2021
Author(s)
Shaibai K. Sarkar, Shifi Kababya, Shimon Vega, Hagal Cohen, Joseph Woicik, A I. Frenkel, Gary Hodes
Chemical bath deposited PbSe films were subjected to post-deposition treatment with aqueous (typically 0.25 - 0.5 M) KOH. For films deposited using a citrate complex, this treatment resulted in dissolution of surface lead oxides (seen from XPS and EXAFS

Efficient Computation of Optical Forces With the Coupled Dipole Method

October 12, 2021
Author(s)
P C. Chaumet, Adel Rahmani, A Sentenac, Garnett W. Bryant
We present computational techniques to compute in an efficient way optical forces on arbitrary nanoobjects using the coupled dipole method. We show how the time of computation can be reduced by several orders of magnitude with the help of fast-Fourier

Elastic Modulus Measurements in Plasma Sprayed Deposits

October 12, 2021
Author(s)
Jay S. Wallace, J Ilavsky
A technique has been developed to characterize the elastic modulus of zirconium oxide-8% yttrium oxide plasma sprayed deposits. A commercial hardness indenter has been modified to record load-displacement as a spherical ball is elastically loaded onto the

Electro-optically derived millimeter-wave sources with phase and amplitude control

October 12, 2021
Author(s)
Bryan Bosworth, Nick Jungwirth, Kassi Smith, Jerome Cheron, Franklyn Quinlan, Ari Feldman, Dylan Williams, Nate Orloff, Chris Long
Integrated circuits are building blocks in millimeter-wave handsets and base stations, requiring nonlinear characterization to optimize performance and energy efficiency. Today's sources use digital-to-analog converters to synthesize arbitrary electrical

Electron Backscatter Diffraction Investigation of a Nano-Crystalline Pt Thin Film

October 12, 2021
Author(s)
T Maitland, X Han, Mark D. Vaudin, G R. Fox, M Coy
A polycrystalline Pt thin film deposited on a cut Si single crystal wafer coated with SiO2 and a TiO2 adhesion layer was studied using automated electron backscatter diffraction (EBSD). Integration of the EBSD detector and a scanning electron microscope

Electron Impact Total Ionization Cross Sections of CF 4 , C 2 F^6^ and C 3 F^8^

October 12, 2021
Author(s)
H Nishimura, W M. Huo, Yong Sik Kim, M A. Ali
Both theoretical and experimental electron-impact total ionization cross sections of CF 4, C 2F 6 and C 3F 8 are presented. The experimental cross sections have been measured as a function of incident electron energy T from threshold to 3 keV. A parallel

Energy-Based Design Approach for Seismic Design: Energy Spectra

October 12, 2021
Author(s)
P Khashaee, B Mohraz, Fahim H. Sadek, Hai S. Lew, John L. Gross
Among the approaches that the Structural Engineers Association of California has recommended for performance based seismic design is the energy approach. In this approach, the earthquake input energy transmitted to the structure is estimated from ground
