Asymmetric Enhanced Intermixing in Co/Ti Bilayer

October 12, 2021
Author(s)
P Sule, L Kotis, L Toth, M. Menyhard, William F. Egelhoff Jr.
… Low-energy ion-beam intermixing has been studied by Auger depth … the occurrence of the asymmetry of intermixing at 2 keV ion energy. At lower ion energies the asymmetry vanishes progressively with the …

Effect of ''glancing'' collisions in the cold atom vacuum standard

February 12, 2025
Author(s)
Stephen Eckel, Daniel Barker, James A. Fedchak, Jacek Klos, Julia Scherschligt, Eite Tiesinga
… enough kinetic energy to eject an ultracold atom from its trap. Our model is wholly probabilistic and shows that the number of the ultracold atoms remaining in the trap as a function of time is nonexponential. We update the … up to 0.6 %. Likewise, we find that in the limit of zero trap depth, the experimentally extracted loss rate …

Photodetectors: High-Gain and Low-Driving-Voltage Photodetectors Based on Organolead Triiodide Perovskites (Adv. Mater. 11/2015)

March 12, 2015
Author(s)
Riu Dong, Yanjun Fang, Jungseok Chae, Jun Dai, Zhengguo Xiao, Qingfeng Dong, Yongbo Yuan, Andrea Centrone, Xiaocheng Zeng, Jinsong Huang
Methylammonium lead triiodide (CH3NH3PbI3) perovskite is an emerging low-cost, solution processable material which attracts great interest for enabling the fabrication of high performance optoelectronic devices such as solar cells, room temperature lasers

A thickness-shear MEMS resonator employing electromechanical transduction through a coplanar waveguide

May 21, 2012
Author(s)
Ward L. Johnson, Thomas M. Wallis, Pavel Kabos, Eduard Rocas, Juan C. Collado Gomez, Li-Anne Liew, Albert Davydov, Alivia Plankis, Paul R. Heyliger
The design, modeling, fabrication, and characterization of a vibrationally trapped thickness-shear MEMS resonator is presented. This device is intended to avoid various limitations of flexural MEMS resonators, including nonlinearity, clamping losses

A Phase-Field Model With Convection: Numerical Simulations

December 1, 2000
Author(s)
D M. Anderson, Geoffrey B. McFadden, A A. Wheeler
In a previously developed phase-field model of solidification that includes convection in the melt, the two phases are represented as viscous liquids, where the putative solid phase has a viscosity much larger than the liquid phase. In this paper we report

End States in One-Dimensional Chains

February 4, 2005
Author(s)
Jason Crain, Daniel T. Pierce
… atom chains that were self-assembled by depositing gold on the vicinal Si(553) surface. Scanning tunneling …

Probing Accelerated Salt-Induced Relaxation Dynamics of Laponite Suspensions Using X-Ray Photon Correlation Spectroscopy Measurements and Molecular Dynamics Simulations

December 22, 2022
Author(s)
Sohaib Mohammed, Meishen Liu, Qingteng Zhang, Suresh Narayanan, Fan Zhang, Greeshma Gadikota
… followed by CsCl and MgCl2 salts. The competing effects of ion size and charge on the relaxation behavior are noted. For … ions shows that higher charge dominates the size of the ion. The trends in the relaxation behavior are consistent … suspensions is accelerated in the presence of salts, with ion sizes and charges having a competing effect on the …
