How to make bright quantum dots even brighter

Quantum dots are a kind of artificial atom: just a few nanometers in size and made of semiconductor materials, they can emit light of a specific color or even single photons, which is important for quantum technologies. The ...

Graphene grows—physicists find a way to visualize it

Graphene is one of the strongest materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the ...

Mix of X-ray methods offers improved structure analysis

Sometimes scientists have to accept that a method they have used for years fails under certain conditions. Such a failure calls for a careful analysis of the shortcomings and their subsequent elimination. An international ...

A non-invasive way to image Wigner crystals directly

A team of researchers at the University of California at Berkeley, working with a group at Lawrence Berkeley National Laboratory, has developed a non-invasive way to image Wigner crystals directly. In their paper published ...
