TL;DR: In this paper, an engineered enhancement of optical absorption and photocurrent in a semiconductor via the excitation of surface plasmon resonances in spherical Au nanoparticles deposited on the semiconductor surface was reported.

TL;DR: In this paper, an engineered enhancement in short-circuit current density and energy conversion efficiency in amorphous silicon p-i-n solar cells was achieved via improved transmission of electromagnetic radiation arising from forward scattering by surface plasmon polariton modes in Au nanoparticles deposited above the polysilicon film.

TL;DR: In this article, the electromagnetic interaction between Au nanoparticles positioned atop a Si pn junction photodiode and incident electromagnetic plane waves has been performed as a function of wavelength, leading to increased electromagnetic field amplitude within the semiconductor and consequently increased photocurrent response, over a broad range of wavelengths extending upward from the nanoparticle surface plasmon polariton resonance wavelength.

TL;DR: It is shown that a silicon-based photocathode with a capping epitaxial oxide layer can provide efficient and stable hydrogen production from water and be highly dependent on the size and spacing of the structured metal catalyst.

TL;DR: In this article, electron concentration profiles have been obtained for AlxGa1−xN/GaN heterostructure field effect transistor structures and the measured electron distributions demonstrate the influence of piezoelectric effects in coherently strained layers on III-V nitride heterostructures device characteristics.
