Journal ArticleDOI
Photonic band structure: The face-centered-cubic case employing nonspherical atoms.
TL;DR: A practical, new, face-centered-cubic dielectric structure which simultaneously solves two of the outstanding problems in photonic band structure and lends itself readily to microfabrication on the scale of optical wavelengths.
Journal ArticleDOI
30% external quantum efficiency from surface textured, thin‐film light‐emitting diodes
TL;DR: In this article, the authors showed that by separating thin-film LEDs from their substrates (by epitaxial lift-off, for example), it is much easier for light to escape from the LED structure and thereby avoid absorption.
Journal ArticleDOI
Unusually low surface-recombination velocity on silicon and germanium surfaces.
TL;DR: It is found that a standard, widespread, chemical-preparation method for silicon, oxidation followed by an HF etch, results in a surface which from an electronic point of view is remarkably inactive, which has implications for the ultimate efficiency of silicon solar cells.
Journal ArticleDOI
Extreme selectivity in the lift‐off of epitaxial GaAs films
TL;DR: In this paper, conditions for the selective lift-off of large area epitaxial AlxGa1−xAs films from the substrate wafers on which they were grown were discovered.
Journal ArticleDOI
Donor and acceptor modes in photonic band structure.

TL;DR: Three-dimensionally periodic dielectric structures, photonic crystals, possessing a forbidden gap for electromagnetic wave propagation, a photonic band gap, are known, and it is now possible to make high-Q electromagnetic cavities of \ensuremath{\sim}1 cubic wavelength, for short wavelengths at which metallic cavities are useless.
