Optical properties of materials are based on their chemistry and the inherent subwavelength architecture, although the latter remains to be characterized in depth. Photonic crystals and metamaterials have proven this by providing ...
(Phys.org) —In photovoltaics, there is generally a trade-off in terms of semiconductor thickness, with thicker semiconductors offering better photon absorption and thinner ones offering higher charge carrier extraction ...
(PhysOrg.com) -- In a new study, scientists have shown that simply tailoring the nanoscale geometrical parameters of dielectric structures can result in an increase in the light intensity to unprecedented levels. Theoretically, ...
(PhysOrg.com) -- While words such as "powerful" and "efficient" are often used to describe the potential of quantum computing, these quantum systems can be very fragile at the same time. Errors in quantum systems can easily ...
(PhysOrg.com) -- "Carbon nanotubes have a lot of really nice properties that make them good for photonics," Laurent Vivien tells PhysOrg.com. Ever since the discovery that carbon nanotubes have photoluminescence when encapsulated ...
Tailored metal nanoclusters can be actively developed in the lab to manipulate light at the subwavelength scale for nanophotonic applications. However, their precise molecular arrangement in a hotspot with fixed numbers and ...
(Phys.org) —Researchers at King's College London have achieved previously unseen levels of control over the travelling direction of electromagnetic waves in waveguides. Their ground-breaking results could have far-reaching ...
