A Florida State University research team has developed a new way to create blue light from a class of materials that shows enormous potential for optoelectronic devices, including solar cells, light-emitting diodes (LEDs) ...
Researchers have designed smart, color-controllable white light devices from quantum dots—tiny semiconductors just a few billionths of a meter in size—which are more efficient and have better color saturation than standard ...
An international team of researchers has developed a new type of strong and elastic two-dimensional (2D) membrane. The invention could prove useful, for instance, in detecting remnants of antibiotics from water.
One of the most important elements in photonic chips or quantum chips is the optical waveguide. However, due to limitations in existing fabrication methods, it is tricky to efficiently produce waveguides with high precision ...
Assembling Lego-like, 2D heterostructures can give rise to emergent properties and functionalities very different from the intrinsic characteristics of the constituents.
The development of high-speed strobe-flash photography in the 1960s by the late MIT professor Harold "Doc" Edgerton allowed us to visualize events too fast for the eye—a bullet piercing an apple, or a droplet hitting a pool ...
The past few decades have witnessed a great amount of research in the field of two-dimensional (2D) materials. As the name implies, these thin film-like materials are composed of layers that are only a few atoms thick. Many ...
Pb-free all-inorganic halide double perovskites (DPs) have emerged as an important class of environmentally benign phosphors for optoelectronic applications. The studies on them are mainly restricted to the visible spectral ...
Raman spectroscopy, an optical microscopy technique, is a non-destructive chemical analysis technique that provides rich molecular fingerprint information about chemical structure, phase, crystallinity, and molecular interactions. ...
Organic thin-film transistors (OTFTs) are the basic building blocks for flexible and stretchable electronics. As organic semiconductor films usually contain significant structural and energetic disorder, charge carriers hop ...
