High-speed atomic force microscopy (HS-AFM) is an imaging technique that can be used for visualizing biological processes, for example the activity of proteins. Nowadays, typical HS-AFM frame rates are as high as 12 frames ...
NUS physicists have discovered a theoretical behavior known as the "critical skin effect" influencing how changes between different phases of matter occur.
Conjugated polymers are organic macromolecules that are characterized by a backbone chain of alternating double and single bonds. Their overlapping p-orbitals create a cloud of delocalised π-electrons, which can result in ...
Light can partake in peculiar phenomena at the nanoscale. Exploring these phenomena can unlock sophisticated applications and provide useful insights into the interactions between light waves and other materials.
Topological insulators have been an exciting field of research with fundamental interest as well as practical applications such as robust transport of electrons and light, and topological quantum computing. The hallmark of ...
In physics, they are currently the subject of intensive research; in electronics, they could enable completely new functions. So-called topological materials are characterized by special electronic properties, which are also ...
The applications of topological photonics have been intensively investigated, including one-way waveguide and topological lasers. The topological lasers especially have attracted broad attention in recent years, which have ...
Topological insulators (TIs) have an insulating interior and support conducting surface states with additional interfacing properties. The exotic metallic states on their surfaces can provide new routes to generate new phases ...
Scientists at Ames Laboratory, Brookhaven National Laboratory, and the University of Alabama Birmingham have discovered a light-induced switching mechanism in a Dirac semimetal. The mechanism establishes a new way to control ...
The all-optical switch is a kind of device that controls light with light, which is the fundamental building block of modern optical communications and information processing. Creating an efficient, ultrafast, and compact ...
