Lasers, devices that emit light in one direction, with photons traveling at one specific frequency and all with the same phase (coherent), govern the way we communicate today.
Quantum dot light-emitting diode, which employs quantum dots as a light-emitting material, has attracted significant attention as a promising alternative for next-generation display technologies, owing to its outstanding electroluminescence properties.
As recently as 2019, spin defects known as qubits were discovered in 2D materials (hexagonal boron nitride), which could amplify the field of ultrathin quantum sensing.
In a new review article in Nature Photonics, scientists from Los Alamos National Laboratory assess the status of research into colloidal quantum dot lasers with a focus on prospective electrically pumped devices, or laser diodes.
Researchers from National Taiwan Normal University and Kyushu University have come up with a new device that requires only a single semiconductor called perovskite to concurrently store and visually transmit data.
'Growing' electronic components directly onto a semiconductor block avoids messy, noisy oxidation scattering that slows and impedes electronic operation.
In a new publication from Opto-Electronic Advances, researchers led by Professor Han Zhang from Shenzhen University, Shenzhen, China, consider whether boron quantum dots surpass the graphene in thermal properties.
A new article in Science magazine gives an overview of almost three decades of research into colloidal quantum dots, assesses the technological progress for these nanometer-sized specs of semiconductor matter, and weighs the remaining challenges on the path to widespread commercialization for this promising technology with applications in everything from TVs to highly efficient sunlight collectors.
A new study published in Science magazine offers an outline of nearly 30 years of research performed on colloidal quantum dots.
Quantum dots are semiconductor particles only a few nanometers across that, thanks to their small size, exhibit peculiar optical and electronic properties due to quantum mechanics.
