TL;DR: Comparison with effective-mass theory shows that the latter is valid for wires wider than 23 A, and first-principles pseudopotential calculations for H-terminated Si wires with thicknesses from 12 to 23 A are performed.
Abstract: We have performed first-principles pseudopotential calculations for H-terminated Si wires with thicknesses from 12 to 23 \AA{}, calculating the band gaps and optical matrix elements. Comparison with effective-mass theory shows that the latter is valid for wires wider than 23 \AA{}. We have used our data to analyze the luminescent properties of highly porous Si fabricated by electrochemical etching of Si wafers in HF-based solutions.

TL;DR: In this paper, a method for the loading and alignment of elastomers in electro-optic and electro-active devices is described, which comprises the in-situ polymerisation between substrates of liquid crystal monomers in the presence of cross-linking reagents.
Abstract: This invention describes a method for the loading and alignment of elastomers in electro-optic and electro-active devices. It comprises the in-situ polymerisation between substrates of liquid crystal monomers in the presence of cross-linking reagents. It also describes the production of free-standing elastomer films.

Journal ArticleDOI
TL;DR: In this article, the authors present a review of intermetallic matrix composites (IMCs), concentrating on the last four years and drawing examples from the three most widely researched matrix systems: titanium aluminides, nickel aluminide and molybdenum disilicide.

TL;DR: The experimental setup consists of an external source of correlated photon pairs which propagate to two widely separated unbalanced Mach-Zehnder interferometers and can be fully modulated by phase plates in either interferometer.
Abstract: We propose an experimental realization of cryptographic-key-sharing scheme exploiting quantum correlations between pair photons. Our experimental setup consists of an external source of correlated photon pairs which propagate to two widely separated unbalanced Mach-Zehnder interferometers. The probability of detection of photon pairs in any two outputs of the interferometers can be fully modulated by phase plates in either interferometer.
