MIT chemists have designed a new type of fluorescent molecule that they hope could be used for applications such as generating clearer images of tumors.
Over the past few years, engineers and material scientists have been trying to devise new optical systems in which light particles (i.e., photons) can move freely and in useful ways, irrespective of defects and imperfections. ...
Atoms in crystalline solids sometimes vibrate in unison, giving rise to emergent phenomena known as phonons. Because these collective vibrations set the pace for how heat and energy move through materials, they play a central ...
In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade.
A research team led by the California NanoSystems Institute at UCLA, or CNSI, demonstrated a new type of light-emitting material expected to be suitable for photonics鈥攄evices based on light in the same way that today's ...
Rice University researchers used a focused electron beam to pattern device functions with submicron precision directly into an ultrathin crystal. The approach produced traces narrower than the width of a DNA helix that glow ...
Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These bound states can give ...
As the volume of scientific literature continues to grow, researchers are turning to artificial intelligence to sift through millions of research papers and uncover insights that can accelerate the discovery of new materials.
Black phosphorus nanoribbons (BPNRs), thin and narrow ribbon-like strips of black phosphorus, are known to exhibit highly advantageous electronic properties, including a tunable bandgap. This essentially means that the energy ...
A new study has successfully demonstrated the confinement of terahertz (THz) light to nanoscale dimensions using a new type of layered material. This could lead to improvements in optoelectronic devices such as infrared emitters ...
