Thin photodetector could increase performance without adding bulk

[caption id="attachment_12670" align="alignnone" width="775"] UW–Madison electrical and computer engineering graduate student Zhenyang Xia holds a dish containing photodetector samples. The sample colors vary depending on how they are tuned to absorb a specific light wavelength.…

New method allows real-time monitoring of irradiated materials

Technique will enable continuous measurement of damage to materials in high-radiation environments. [caption id="attachment_12437" align="alignnone" width="639"] “Our whole goal was to monitor how materials evolve when exposed to radiation,” associate professor Michael Short explains, “but…

Unpolarized single-photon generation with true randomness from diamond

The Tohoku University research group of Professor Keiichi Edamatsu and Postdoctoral fellow Naofumi Abe has demonstrated dynamically and statically unpolarized single-photon generation using diamond. [caption id="attachment_12244" align="alignnone" width="629"] Schematic picture of unpolarized single-photon generation using…

OLYMPUS experiment sheds light on structure of protons

Seven-year study indicates two photons, not one, are exchanged in electron-proton interactions. [caption id="attachment_11681" align="alignnone" width="639"] A mystery concerning the structure of protons is a step closer to being solved, thanks to a seven-year experiment…
