On the Link Between Insertion Loss and Lower Bound of Efficiency

August 9, 2013
Author(s)
Levon Barsikyan, Jason Coder, Mark Golkowski, John M. Ladbury
We investigate the effect of chamber loss on the recently developed 2-port antenna model and the associated method of determining antenna efficiency. The loss in the reverberation chamber was controlled using microwave absorbing foam creating four

Traceability for Aerosol Electrometer in the fA Range

June 1, 2013
Author(s)
Dean G. Jarrett, Miles Owen
Described here are the configurations and procedures used to provide traceability to electrical standards for an aerosol electrometer calibration in the range ± 20 fA to ± 40 fA. The technique used here simulated the condition of a current induced when

The Forthcoming IEEE Standard 1696 on Test Methods for Characterizing Circuit Probes

May 6, 2013
Author(s)
Nicholas Paulter, John Jendzurski, Mike McTigue, Bill Hagerup, Thomas E. Linnenbrink
The Technical Committee 10 (TC10) of the IEEE Instrumentation and Measurement Society initiated a new standards activity in 2006 for the development of test methods to characterize the performance of circuit probes. This standard contains a set of

Graphene as Transparent Electrode for Direct Observation of Hole Photoemission from Silicon to Oxide

March 27, 2013
Author(s)
Rusen Yan, Qin Zhang, Oleg A. Kirillov, Wei Li, James I. Basham, Alexander G. Boosalis, Xuelei X. Liang, Debdeep Jena, Curt A. Richter, Alan C. Seabaugh, David J. Gundlach, Huili G. Xing, Nhan V. Nguyen
The outstanding electrical and optical properties of graphene make it an excellent alternative as a transparent electrode. Here we demonstrate the application of graphene as collector material in internal photoemission (IPE) spectroscopy; enabling the

Organosilicate Polymer E-Beam Resists with High Resolution, Sensitivity and Stability

February 28, 2013
Author(s)
Christopher Soles, Richard Kasica, Hae-Jeong Lee, Jae H. Sim, Sung-Il Lee, Ki-Bum Kim, Hyun-Mi Kim, Do Y. Yoon
Hydrogen silsesquioxane (HSQ) is an attractive electron-beam (e-beam) resist for sub-20 nm lithography due to its high resolution, excellent line-edge-roughness (LER), and good plasma etch resistance. However, the sensitivity and long-term stability of HSQ

Nonlinear acoustic effects in multilayer ceramic capacitors

January 25, 2013
Author(s)
Ward L. Johnson, Sudook A. Kim, Timothy P. Quinn, Grady S. White
Nonlinear resonant acoustics was explored as an approach for nondestructively evaluating the susceptibility of BaTiO3-based multilayer ceramic capacitors to electrical failure during service. The acoustic nonlinearity was characterized through measurements
