Measuring topological invariants is an essential task in characterizing topological phases of matter. Scientist in China implemented the experimental extraction of Zak phase from band structures ...

A new technique for measuring the electronic band structure of solid materials has been unveiled by physicists in Canada. The new method does not require the sample to be placed in a vacuum chamber ...

In the lab: David Allemeier, PhD student and first author on the paper describing the microcavities, checks a new bottle of NPB, which is used as the hole transport layer in the OLEDs. (Courtesy: ...

On the other hand, thanks to the rapid progress in single crystal wafer growth technology in recent years, it has become feasible to obtain highquality crystal samples for the accurate evaluation of ...
