Optical dielectric function of silver
Honghua Yang,Jeffrey D'Archangel,Michael L. Sundheimer,Eric Tucker,Glenn D. Boreman,Markus B. Raschke +5 more
TL;DR: Using broadband spectroscopic ellipsometry, the complex valued dielectric function of silver films from 0.05 eV to 4.14 eV with a statistical uncertainty of less than 1% was determined in this article.

A Proposed Quantum Mechanics Mechanism for (e-, h+) Charges Separation Applied to Photosynthesis and Energy Production Efficiency Improvement
M. Sacilotti,Euclides Almeida,Cláudia C. B. O. Mota,Frederico Dias Nunes,Michael L. Sundheimer +4 more
TL;DR: In this article, a qualitative model for the first step mechanism in artificial catalysis and natural systems such as photosynthesis in green leaves is proposed based on concepts in semiconductor band gap engineering (the staggered one).
