Optics in the City of Light: C2N proud to host tomorrow’s scientific talents

The C2N is very proud to have been one of the host laboratories for the program Optics in the City of Light – Research Experience for Undergraduates (REU), which offers U.S. undergraduate students the opportunity to gain hands-on experience in cutting-edge research within laboratories of the Paris region. Among them was Hannah Lias, a student at the South Dakota School of Mines and Technology. For two months, under …

Electric-field-assisted phase switching for crystal phase quantum dot fabrication in GaAs nanowires

Researchers at C2N and the National University of Singapore have demonstrated a new way to control the crystal structure of semiconductor nanowires using an electric field, paving the way for the on-demand fabrication of crystal-phase quantum dots. Controlling different crystal phases within nanowires presents both a challenge and an opportunity. While unwanted phase mixing can degrade device quality, deliberately controlling these phases can be used to create new quantum …
