The frequency regime lying in the shortwave infrared (SWIR) has very unique properties that make it ideal for several applications, such as being less affected by atmospheric scattering as well as being "eye-safe." These ...
Researchers from Pohang University of Science and Technology (POSTECH) and the University of Montpellier have successfully synthesized wafer-scale hexagonal boron nitride (hBN) exhibiting an AA-stacking configuration, a crystal ...
When light interacts with metallic nanostructures, it instantaneously generates plasmonic hot carriers, which serve as key intermediates for converting optical energy into high-value energy sources such as electricity and ...
A group of Carnegie Mellon University researchers recently devised a method allowing them to create large amounts of a material required to make two-dimensional (2D) semiconductors with record high performance. Their paper, ...
Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by excited particles, due to photons of the same frequency triggering further emissions. This phenomenon ...
Light-emitting diodes (LEDs) are widely used electroluminescent devices that emit light in response to an applied electric voltage. These devices are central components of various electronic and optoelectronic technologies, ...
Colloidal self-assembly is a process where colloidal particles spontaneously organize into ordered structures under specific conditions. Colloidal self-assembly serves as a foundation for designing materials like optoelectronic ...
Next-generation imaging technology is rapidly expanding beyond smartphones into intelligent devices, robotics, extended reality (XR) devices, health care, CCTV, and various other industries. At the core of these technological ...
Composite adhesives like epoxy resins are excellent tools for joining and filling materials including wood, metal, and concrete. But there's one problem: once a composite sets, it's there forever. Now there's a better way. ...
A research team at POSTECH has developed a method for synthesizing perovskite nanocrystals (PNCs), a next-generation semiconductor material, in a more uniform and efficient manner. This study is expected to serve as a key ...
