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.
Hold on there, graphene. Seriously, your grip could help make better catalysts.
So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range.
It may be possible in the future to use information technology where electron spin is used to store, process and transfer information in quantum computers. It has long been the goal of scientists to be able to use spin-based quantum information technology at room temperature.
Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots' light-producing efficiency.
A new class of quantum dots deliver a stable stream of single, spectrally tunable infrared photons under ambient conditions and at room temperature, unlike other single photon emitters. This breakthrough opens a range of practical applications, including quantum communication, quantum metrology, medical imaging and diagnostics, and clandestine labeling.
Curtin University has played a major role in the recovery of a rare meteorite in the UK, made possible by dedicated fireball observatories set up as part of the Curtin-led Global Fireball Observatory (GFO).
Tiny fluorescent semiconductor dots, called quantum dots, are useful in a variety of health and electronic technologies but are made of toxic, expensive metals. Nontoxic and economic carbon-based dots are easy to produce, but they emit less light.
A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan.
Q-CTRL, a startup that applies the principles of control engineering to power quantum technology, today announced it will provide the first quantum sensing and navigation technologies for space exploration beginning with uncrewed lunar missions by the SEVEN SISTERS space industry consortium in Australia.
