Thermal scientists from the Iowa State University, Shenzhen University, and Shanghai University of Engineering Science, have developed a new thermal probing technique based on the ratio of two resonance Raman scattering peak ...
Excitons are quasiparticles that are formed in insulators or semiconductors when an electron is promoted to a higher energy band, leaving a positively charged hole behind.
Two-dimensional materials, which consist of a single layer of atoms, exhibit unusual properties that could be harnessed for a wide range of quantum and microelectronics systems. But what makes them truly special are their ...
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. ...
A group of scientists working on surface-enhanced Raman spectroscopy (SERS) has made a nanoruler to provide insight into the longitudinal plasmonic fields in nanocavities, according to research published in the Journal of ...
Atomically thin semiconductors such as molybdenum disulfide and tungsten disulfide are promising materials for nanoscale photonic devices. These approximately 2D semiconductors support so-called excitons, which are bound ...
A rare spectroscopy technique performed at Swinburne University of Technology directly quantifies the energy required to bind two excitons together, providing for the first time a direct measurement of the biexciton binding ...
Solar panels, cameras, biosensors and fiber optics are technologies that rely on photodetectors, or sensors that convert light into electricity. Photodetectors are becoming more efficient and affordable, with their component ...
Typically only an atom thick, 2D materials exhibit highly desirable properties for advanced technologies, such as flexibility, superconductivity and more. Made from carefully transitioning individual components from gas or ...
As silicon based semiconducting technology is approaching the limit of its performance, new materials that may replace or partially replace silicon in technology is highly desired. Recently, the emergence of graphene and ...
