Switchable materials that have extreme material contrast and short switching times with negligible degradation can contribute to active plasmonic and nanophotonic systems. In order to understand their supreme properties, ...
Quantum optics, spintronics and diffraction-free imaging with low loss are among the technologies that may benefit from recently predicted effects in twisted bilayer photonic structures. The work takes inspiration from a ...
DNA data storage may become easier to read and write than before, according to researchers at the University of Cambridge Cavendish Laboratory in the U.K. They report on a technique that can also store encrypted data, as ...
Soliton descriptions for the conducting polymers polyacetylene—descriptions based around a type of solitary wave—caused great excitement when they first broke in the seminal reports by Su, Schrieffer, Heeger (SSH) and Kivelson ...
Microfluidic paper-based analytical devices (µPADs) are a promising concept with rapid development in recent years. In a new study published on Nature: Microsystems & Nanoengineering, a team led by Yanfang Guan and Baichuan ...
The first demonstration of graphene double quantum dots in which it is possible to control the number of electrons down to zero has been reported in Nano Letters. Far from an abstract academic stunt, the results could prove ...
Materials that exhibit topological phases can be classified by their dimensionality, symmetries and topological invariants to form conductive-edge states with peculiar transport and spin properties. For example, the quantum ...
Organic-inorganic halide perovskite quantum dots (PQDs) form an attractive class of materials for optoelectronic applications. Their charge transport properties are, however, inferior compared to materials such as graphene. ...
The electronics industry might look very different today were it not for the dramatic drop in cost of high-quality single-crystalline silicon wafers over the past five decades. So what would happen if the cost of single-crystalline ...
Despite the progress in perovskite device efficiencies, these systems are not fully understood, in particular the frequency- and power-dependence of their response to light. Yu-Hwa Lo and colleagues at the University of California ...
