Enhancing molecular flux through nanopores via attractive interactions

November 1, 2006
Author(s)
John J. Kasianowicz, Tam Nguyen, Vincent M. Stanford
The classic experiments by Galvani and his colleagues in the 1790s led him to suggest that neural conduction and muscle contraction are governed by a form of animal electricity. Nearly 100 years later, Santiago Ramon y Cajal?s use of Golgi stains provided

On the Use of Reverberation Chambers to Simulate a Controllable Rician Radio Environment for the Testing of Wireless Devices.

Christopher L. Holloway, David A. Hill, John M. Ladbury, Perry F. Wilson, Galen H. Koepke, Jason Coder
With the proliferation of wireless devices in recent years, there is a growing need to test the operation and functionality of these various devices in different multipath radio propagation environments, ranging from a direct line-of-sight environment to a

Quantum dot single photon sources studied with superconducting single photon detectors

November 1, 2006
Author(s)
Martin Stevens, Robert Hadfield, Sae Woo Nam, Richard Mirin
We report the observation of photon antibunching from a single, self-assembled InGaAs quantum dot (QD) at temperatures up to 135 K. The second-order intensity correlation, g (2)(0), is less than 0.260 +or-} 0.024 for temperatures up to 100 K. At 120 K, g
