  • The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this in CuCrP2S6, a van der Waals material that transitions from a noncentrosymmetric to a centrosymmetric average structure. […]
  • Researchers have demonstrated a technique that uses a laser to produce a plasma beam antenna capable of transmitting radio waves. The article, "Laser-Induced-Plasma-Filament Antenna Transmitting 30 MHz VHF," is published in the IEEE Journal of Microwaves.

IMAKS is preparing for power outage

All power will be down on NCSU Centennial campus starting at 7:30 a.m. on Sunday, June 2 . The crews will connect power lines to newly constructed buildings. As a result, all instruments have to be powered down and unplugged from wall outlets.

Lab temperature today

The facilities were planning to do work on secondary power lines (emergency lights, signs, and such). Accidentally, this morning they switched off the HVAC system and lab hoods. As a result, the lab got hot beyond the operating range of ultrafast lasers. facilities have been contacted. The temperature is getting to normal now. We anticipate we can start running experiments around 11 a.m.
