A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

Scientists have reviewed the superconducting diode effect, a quantum effect enabling dissipationless supercurrent to flow in only one direction. The SDE provides new functionalities for ...

In this work we investigate the role of threading dislocations in nitride light emitters with different indium composition. We compare the properties of laser diodes grown on the low defect density ...

On the outskirts of Germany's Bavarian capital Munich, in a small block within a business park, two employees share an office. Not exactly an unusual scenario, you might think, but Wilhelm Kaenders ...

Tokyo — A team of University of California, Santa Barbara (UCSB), researchers led by Shuji Nakamura, a pioneer of laser diode science, has created a low-threshold-current, nonpolar blue-violet laser ...

The voltage-current density, luminance and EL spectra were measured with a programmable source meter (Keithley 2400), luminance meter (LS110, Konica Minolta) and a spectrophotometer (Spectrascan PR670 ...

The data usage of the modern world is absolutely mind-boggling. We have giant, air-conditioned buildings dedicated to shuffling bits around at high speed. And for what? To ensure that Instagram can ...

In a new report on Science Advances, Hsinhan Tsai and a research team in materials, nanotechnology, nuclear engineering and X-ray science at the Los Alamos National Laboratory and the Argonne National ...

SAN FRANCISCO — A team of University of California-Santa Barbara (UCSB) researchers led by Shuji Nakamura, a pioneer of laser diode science, have created a new type of blue-violet laser diode that ...
