Surfaces, Interfaces, and Changing Shapes

October 16, 2008
Author(s)
Daniel Josell, F Spaepen
It is generally recognized that the capillary forces associated with internal and external interfaces affect both the shapes of liquid-vapor surfaces and wetting of a solid by a liquid. It is less commonly understood that the same phenomenology often

NBTI: Confusion, Frustration, and Promise?

May 2, 2010
Author(s)
Jason P. Campbell
The negative-bias temperature instability (NBTI) is a reliability problem that, in the last ten years, has risen from relative obscurity to become the most important reliability problem in advanced pMOSFET devices. Even though a significant effort has been

Fresh Concrete Rheology - Recent Developments

December 1, 2001
Author(s)
Chiara F. Ferraris, F De Larrard, Nicos Martys
The design of concrete with specified properties for an application is not a new science, but it has taken on a new meaning with the wide use of high performance concretes. The following properties are related to fresh concrete: ease of placement and

On the scalability of parametric down-conversion for generating higher-order Fock states

October 18, 2018
Author(s)
Thomas Gerrits, Adriana Lita, Sae Woo Nam, Johannes Tiedau, Tim J. Bartley, Georg Harder, Christine Silberhorn
Spontaneous parametric down-conversion (SPDC) is the most widely-used method to generate higher-order Fock states (n>2). Yet, a consistent performance analysis from fundamental principles is missing. Here we address this problem by analyzing state fidelity

Identifying spurious modes in RF-MEMS resonators using photoelastic imaging

January 21, 2018
Author(s)
Vikrant J. Gokhale, Jason J. Gorman
This paper reports the first use of dynamic photoelastic imaging for identifying in-plane vibration modes in high-frequency MEMS resonators. In a set of width-extensional mode resonators (WE-BARs), we map fundamental width-extensional modes and unwanted

Calibration-Kit Design for Millimeter-Wave Silicon Integrated Circuits

July 1, 2013
Author(s)
Dylan F. Williams, Phillip Corson, Sharma Jahnavi, Krishnaswamy Harish, Tai Wei, George Zacharias, Ricketts David, Watson Paul, Dacquay Eric, Voinigescu Sorin
… lines with meshed ground plane. We also develop a gold plating process that greatly improves contact repeatability, …

Broadband Emissivity Calibration of Highly Reflective Samples at Cryogenic Temperatures

October 15, 2012
Author(s)
Solomon I. Woods, Timothy M. Jung, Greg Ly, Simon G. Kaplan, Jie Yu
We have developed a technique for calibrating the broadband optical emissivity of high reflectivity samples at cryogenic temperatures. This measurement method employs a primary standard optical detector with high absorptance from visible wavelengths to
