Scientists have developed a sheet of graphene material with minuscule holes in it that they could then place on a gold substrate. The holes allow molecules to attach to the gold exactly where the scientists want them, creating patterns that control the physical shape and electronic properties of nanoscale devices.
Metamaterials can be used to manipulate light for a range of applications, but often require complicated three-dimensional structures with features as small as a few tens of nanometers. Now, researchers have constructed a simpler, two-dimensional metasurface for state-of-the-art high-transmission light manipulation.
The design of photo-bioelectrochemical cells based on native photosynthetic reaction is attracting substantial recent interest as a means for the conversion of solar light energy into electrical power.
Researchers have created nanoribbons of an emerging class of materials called topological insulators and used a magnetic field to control their semiconductor properties, a step toward harnessing the technology to study exotic physics and building new spintronic devices or quantum computers.
Researchers have found a solution to the problem of overheating of active plasmonic components. They demonstrate how to efficiently cool optoelectronic chips using industry-standard heatsinks in spite of high heat generation in active plasmonic components.
