uses of Small Particle Growth in Silane Discharges

October 16, 2008
Author(s)
G Bano, K Rozsa, Alan Gallagher
Silicon-based particles that grow in a silane radio frequency (RF) discharge are studied by light scattering. Average particle size and the corresponding particle density are measured as functions of silane density, RF voltage, and chamber temperature (t)

Using Outcome Tracking to Plan Our E-Journal Future

October 16, 2008
Author(s)
Barbara P. Silcox
This session will address how the NIST Research Library uses customer data to make collection development decisions. The presentation will briefly describe the survey instruments used and techniques employed to obtain input from NIST researchers on the

Validated Sheath Model for Radio-Frequency-Biased, High-Density Plasmas

October 16, 2008
Author(s)
Mark Sobolewski
A model is proposed for sheaths in high-density plasma discharges, with radio-frequency bias applied at frequencies (omega) comparable to (omega sub i), the ion plasma frequency at the edge of the sheath. The model treats ion dynamics using fluid equations

Virtual-Real Quantum Interference in a Semiconductor System

October 16, 2008
Author(s)
H Ahn, S B. Choe, D S. Kim, J M. Shacklette, Y S. Lim
Probabability amplitude in the upper state can be induced by the off-resonant, virtual excitations as well as by the resonant, real excitations. Bytwo-color pulse shaping, we simultaneously create virtual and real amplitudes for excitons in GaAs quantum

Visualization Technique for Uncertainty Budgets: Onion Charts

October 16, 2008
Author(s)
Kenneth W. Pratt, David L. Duewer
A concise graphical depiction, the onion chart, is described for presenting uncertainty budgets for any measurand, y, having a set of component variances, ui2(y). The onion chart consists of a concentric series of rings. Each ring is constructed from the

Vortices, Antivortices and Superfluid Shells Separating Mott-Insulating Regions

October 16, 2008
Author(s)
Kaushik Mitra, Carl J. Williams, Carlos Sa de Melo
Atomic or molecular bosons in harmonically confined optical lattices are found to exhibit a wedding cake structure consisting of insulating (Mott) and superfluid shells. It is found that the order parameter equation in the superfluid regions is not of the
