InN Layers Grown by HVPE

October 12, 2021

Author(s)

A Syrkin, V Ivantsov, A Usikov, Vladimir A. Dmitriev, G Chambard, P Ruterana, Albert Davydov, Siddarth Sundaresan, E Lutsenko, A V. Mudryi, E D. Readinger, G D. Chern-Metcalfe, M Wraback

We report on the first time demonstration and properties of high quality HVPE InN and on successful subsequent MBE growth of InN layers with improved characteristics on template substrates. InN layers were grown on GaN/sapphire HVPE grown templates. The

R Behrens, K Helmstadter, P Ambrosi, J M. Bordy, C Lecante, M Bovi, I Jokelainen, Christopher G. Soares, P R B Saull, A Kharitonov, S Fedina, T Kurosawa, M Kato

The first EUROMET comparison for the standards for absorbed dose rate in 0.07 mm tissue depth for beta radiation of eight national metrology institutes has been completed. The participants were LNE-LNHB (FR), ENEA (IT), STUK (FI), PTB (DE), and four

Interface-Anisotropy Induced Asymmetry of Intermixing in Bilayers

October 12, 2021

Author(s)

P Sule, M. Menyhard, L Kotis, J Labar, William F. Egelhoff Jr.

The ion-sputtering induced intermixing is studied by molecular dynamics (MD) simulations and by Auger electron spectroscopy depth profiling (AES-SP) analysis in PT/Ti/Si (Pt/Ti) and Ta/Ti/Pt/Si(Ti/Pt) bilayers. Experimental evidence is found for the

Investigation of Different Growth Steps in the Preparation of Layer-by-Layer Self-Assembled Films by Second Harmonic Generation

October 12, 2021

Author(s)

M Breit, M Gao, G von Plessen, J Lemmer, J Feldman, Steven T. Cundiff

Second harmonic generation (SHG) is used to investigate various growth steps in the preparation of layer-by-layer self-assembled films of oppositely charged polyelectrolytes. Two very important steps in the film preparation, namely the adsorption and

Investigation of the State of Water in Hydrating Layered and Amorphous Sodium Disilicate (Alkali-Silica Reactants) by Quasi-Elastic Neutron Scattering

October 12, 2021

Author(s)

J W. Phair, Richard A. Livingston, Craig Brown

The structure and state of water within hydrating layered and amorphous sodiumdisilicate were monitored for the first time using quasi-elastic neutron scattering (QENS) and x-ray diffraction (XRD). The QENS kinetic data collected for the first 12 hours of

Investigation of the Subcritical Crack Growth Process in Glass by Atomic Force Microscopy

October 12, 2021

Author(s)

Jean-Pierre Guin, Sheldon M. Wiederhorn

To investigate the possibility of cavity formation in silica glass during subcritical crack growth, the topography of fracture surfaces formed in water at a crack velocity of 8.10-11 m/s was mapped using an atomic force microscope. The objective of the

Ionization Cross Sections by Electron Impact of Halogen Atoms, Diatomic Halogen and Hydrogen Halide Molecules

October 12, 2021

Author(s)

M A. Ali, Yong Sik Kim

The Binary-Encounter-Bethe (BEB) model has been applied to calculate electron impact ionization cross sections of Br, I, Br2, I2, HCl, HBr and HI. The BEB single ionization cross sections of Br and I presented here and also of Cl and Cl2, as reported

Ionization of W and W+ by Electron Impact

October 12, 2021

Author(s)

D H. Kwon, Y J. Rhee, Yong Sik Kim

Theoretical cross sections for electron-impact ionization of the neutral W atom and W$^+$ ion are reported. The direct ionization cross sections were calculated by using the binary-encounter Bethe (BEB) model and the indirect ionization cross sections

Isochoric Heat Capacities of Ethanol-Water Mixtures at Temperatures from 280 K to 420 K and Pressures to 30 Mpa

October 12, 2021

Author(s)

Hiroshi Kitajima, N Kagawa, S Tsuruno, Joe W. Magee

Specific heat capacity at constant volume is one of the most important thermodynamic properties to develop and evaluate thermodynamic equations of state. With this viewpoint, isochoric heat capacities of ethanol-water mixtures have been measured with a

Isothermal Kovats Retention Indices of Sulfur Compounds on Poly (5% Diphenyl/95% Dimethylsiloxane) Stationary Phase

October 12, 2021

Author(s)

K E. Miller, Thomas J. Bruno

Isothermal Kovats retention indices of 21 sulfur compounds relevant to the fuel gas and food industries are reported on a poly (5% diphenyl/95%dimethylsiloxane) capillary column stationary phase. Measurements are performed at four temperatures and the
