Loucas G. Christophorou, James K. Olthoff
… neutrals, total ionization, total electron attachment, and ion pair formation. Similar data on the density-reduced … dissociation into neutrals, electron attachment, and ion-pair formation. A cross section is derived for the total … excitation cross section via low-lying negative ion resonances. Data are suggested for the coefficients for …

Growth morphologies of heteroepitaxial rutile films on sapphire substrates

July 1, 1997
Author(s)
P. A. Morris-Hotsenpiller, Alexana Roshko, J. B. Lowekamp, G. S. Rohrer
… (0 0 1) rutile films grown on sapphire substrates by the ion-beam sputter deposition technique have been examined as a … made between (1 0 0) and (1 0 1) rutile films grown by the ion-beam sputter deposition and metalorganic chemical vapor … deposited films have morphologies which are similar to the ion-beam sputtered films with comparable thicknesses, but …

Characterization of Noise in CMOS Ring Oscillators at Cryogenic Temperatures

July 12, 2023
Author(s)
Prashansa Mukim, Pragya Shrestha, Advait Madhavan, Nitin Prasad, Jason Campbell, Forrest Brewer, Mark Stiles, Jabez J. McClelland
Allan deviation provides a means to characterize the time-dependence of noise in oscillators and potentially identify the source characteristics. Measurements on a 130nm, 7-stage ring oscillator show that the Allan deviation declines from 300K to 150K as

Pumping and decay rates of cold atoms dark states

September 9, 2019
Author(s)
Moshe Shuker, Juniper Pollock, V. I. Yudin, John Kitching, Elizabeth Donley
Coherent dark states in atoms, created by simultaneous interaction of two coherent light fields with an atom, are of prime importance in quantum state manipulation. They are used extensively in quantum sensing and quantum information applications to build

Chip-Scale Atomic Devices

June 4, 2006
Author(s)
John E. Kitching, Svenja A. Knappe, P Schwindt, Ying-ju Wang, Hugh Robinson, Leo W. Hollberg, Li-Anne Liew, John Moreland, Alan Brannon, J Breitbarth, Brad Lindseth, Z Popovic, V Shah, Vladislav Gerginov, Matt Eardley
We present an overview of recent work to develop chip-scale atomic devices such as frequency references and magnetometers. These devices take advantage of advances over the last ten years in the fields of micro electro mechanical systems (MEMS), precision

Resonant Magnetic Field Control of Elastic Scattering in Cold 85Rb

December 1, 1998
Author(s)
J L. Roberts, N R. Claussen, J P. Burke, C H. Greene, Eric A. Cornell, C E. Wieman
A magnetic field-dependent Feshbach resonance has been observed in the elastic scattering collision rate between stoms in the F = 2, M = -2 state of 85Rb. Changing the magnetic field by several Gauss caused the collision rate to vary by a factor of 10 4
