High Inversion Current in Silicon Nanowire Field Effect Transistors

Author(s)
Sang-Mo Koo, Jin-Ping Han, Eric M. Vogel, Curt A. Richter, J. Vahakangas, Akira Fujiwara
Silicon nanowire (SiNW) field effect transistors (FETs) with channel widths down to 20 nm have been fabricated by a conventional 'top-down?approach using...

Standards of time and frequency at the outset of the 21st century

Author(s)
Scott Diddams, James C. Bergquist, Steven R. Jefferts, Christopher W. Oates
In this paper we review state-of-the-art atomic time and frequency standards and discuss some of their uses in science and technology. After fifty years of...

Author(s)
U Sterr, C Degenhardt, H Stoehr, Ch. Lisdat, H Schnatz, J Helmcke, F Riehle, G Wilpers, Christopher W. Oates, Leo W. Hollberg
We describe the current status of the optical calcium frequency standard with laser-cooled neutral atoms realized in two different laboratories for the purpose...

Photoassociative Formation of Ultracold Polar KRb Molecules

Author(s)
Svetlana A. Kotochigova, Eite Tiesinga, Paul S. Julienne
We investigate the effectiveness of creating polar ground state KRb molecules by two-color photoassociative spectroscopy. In this process the molecules are...
