TL;DR: Interference between forward- and backward-propagating waves enhances the light absorption in quarter-wave or deeper subwavelength films, amplifying the intensity close to the surface wherein photogenerated minority charge carriers can reach the surface and oxidize water before recombination takes place.

TL;DR: The hollow ZnO fibers were much more sensitive compared to reference ZnNO thin film specimens, displaying even larger sensitivity enhancement than the 2-fold increase in their surface to volume ratio.

TL;DR: Close packed arrays of hollow SnO2 hemispheres were prepared using PMMA microspheres as sacrificial templates for subsequent sputter-deposition of SnO1 films, leading to a threefold enhancement in gas sensitivity compared to non-templated (flat) films.

TL;DR: This work has shown that during a bioInspired crystallization process, incorporation of amino acids into the crystal structure of ZnO induces lattice strain that leads to linear bandgap shifts, which allows for fine tuning of the bandgap in a bio-inspired route.

TL;DR: It is shown that a stack of several-nanometer-thick layers of alternating high- and low-refractive- index material can result in the localization of light, which could provide a route to manipulating light on the nanometer scale.
