Dielectric Function of Wurtzite GaN and AIN Thin Films

Author(s)
L X. Benedict, Eric L. Shirley, T Wethkamp, K Wilmers, C Cobet, N Esser, W Richter, M Cardona
We present measurements and calculations of the dielectric function of wurtzite GaN and AIN. Spectroscopic ellipsometry was used to determine ε (omega) of thin...

Barium Strontium Titaanate Thin Film Analysis

Author(s)
T Remmel, R Deslattes, S Fujimura, H Honma, H Kobayashi, H Kohno, S M. Owens, J Pedulla, M Schulberg
Barium Strontium Titanate (BST) is under consideration as a high dielectric constant material for a number of semiconductor applications. Because of its very...

Tuning the Mean-Field Energy in a Fermi Gas of Atoms

Author(s)
C A. Regal, Deborah S. Jin
An exotic superfluid phase has been predicted for an ultracold gas of fermionic atoms. Experimenters have cooled these gases into the quantum degenerate regime...

Reciprocal Space Neutron Imaging

Author(s)
D A. Pushin, D G. Cory, Muhammad D. Arif, David L. Jacobson, M Huber
Here we introduce a Fourier based method for phase contrast neutron imag-ing, report its experimental implementation, show results for a 1-D test phan-tom, and...

Tight-Binding Theory of Quantum Dot Arrays: InAs Dots

Author(s)
Javier Aizpurua, G C. Bryant, W Jaskolski
We model the electronic structure and optical properties of coupled self-assembled dots and period dot arrays by use of tight-binding theory. Coupling in dot...
