FT-IR Based Polarimeter with High-Quality Brewster-Angle Polarizers

October 8, 1998
Author(s)
Simon G. Kaplan, Leonard M. Hanssen
A Fourier transform infrared (FT-IR) spectrometer based broadband infrared polarimeter has been developed around a pair of high-quality Brewster angle polarizers. These polarizers consist of four Ge plates in a chevron geometry and have been measured to

Microstuctural Characterization of Hardened Steel by Nondestructive Methods

July 1, 1997
Author(s)
P T. Purtscher, B Igarashi, Donna C. Hurley, K W. Hollman
This paper describes the application of a variety of methods to the nondesctructive characterization (NDC) of microstructure in hardened steels. The measurements include ultrasonic velocity, nonlinear ultrasonics, resonant ultrasonic spectroscopy (RUS)

… polarized neutron reflectometry as in operando probes of ion-gel transistors based on ferromagnetic La 0.5 Sr 0.5 … Ion-Gel-Gating-Induced Oxygen Vacancy Formation in Epitaxial …

Unusual Bias Temperature Instability in SiC DMOSFET

March 3, 2014
Author(s)
Zakariae Chbili, Kin P. Cheung, Jason P. Campbell, John S. Suehle, D. E. Ioannou, Aivars Lelis, Sei-Hyung Ryu
We observe an unusual instability in the SiC DMOSFET transistor characteristics. From a series of bias conditions at elevated temperatures, we conclude that a high density of hole traps in the oxide near the SiO2/SiC interface are responsible.

Really Cool Molecules

October 16, 2008
Author(s)
Paul S. Julienne
Ultracold molecules have been made by applying a time-dependent magnetic field to a dilute quantum gas of ultracold trapped fermionic atoms. This raises the prospect of creating novel superfluids and molecular Bose-Einstein condensates.

A CW calibrated laser pulse energy meter for the range 1 pJ to 100mJ

May 13, 2014
Author(s)
Malcolm G. White, Rodney W. Leonhardt, David J. Livigni, John H. Lehman
… We describe the use of a silicon photodiode trap detector and digital storage oscilloscope as an absolute … of the voltage pulse generated by the photodiode trap detector. We highlight the versatility of the technique …

Circuit Quantum Electrodynamics with a Spin-Orbit Qubit

October 17, 2012
Author(s)
Jacob M. Taylor, Karl Petersson, L. McFaul, M. Schroer, M. Jung, Andrew Houck, Jason Petta
We develop a circuit quantum electrodynamics architecture for spin qubits by coupling an InAs double quantum dot to a high quality factor superconducting cavity. A charge trapped in the double quantum dot interacts with the electric field of the cavity

Unconventional structure-assisted optical manipulation of high-index nanowires in liquid crystals

March 20, 2012
Author(s)
Kristine A. Bertness, David Engstrom, Michael C. Varney, Martin Persson, Rahul P. Trivedi, Mattias Goksor, Ivan I. Smalyukh
Stable optical trapping and manipulation of high-index particles in low-index host media is often impossible due to the dominance of scattering forces over gradient forces. Here we explore optical manipulation in liquid crystalline structured hosts and

Metal-Insulator transition in Doped Barium Plumbate

September 16, 2021
Author(s)
Andreza M. Eufrasio, Ian L. Pegg, Nikolaus Deems, Biprodas Dutta, Winnie Wong-Ng, Qingzhen Huang
Solid solutions in the Ba(Pb1−xSrx)O3−z system were prepared by aliovalent substitution of Pb4+ by Sr2+ ions to investigate the effect of cation stoichiometry on thermal and electrical properties as x was varied between 0 and 0.4, in the temperature range
