The 2026 National Nanowire Days (J2N 2026) will be organized by Pascal Institute (IP) in Clermont-Ferrand from Wednesday, September 30 to Friday, October 2, 2026.

J2N brings together the scientific community working on semiconductor nanowires, primarily but not exclusively.

For the 2026 edition, J2N will be expanded to include the Functionalization axis of the GDR MATEPI as well as the Nanomaterials/Nanowires axis of the GDR NAME.

The objective is to provide an overview of national research activities in crystal growth and nanowire structuring, their advanced characterization, and their integration into devices for all possible application fields.

We will adopt the same format as previous J2N meetings, consisting of four half-days of conference sessions:

• Wednesday, September 30, 2026 – afternoon (starting at 2:00 PM)
• Thursday, October 1, 2026 – full day
• Friday, October 2, 2026 – morning (ending around 1:30 PM)

Please mark these dates in your calendars if you wish to participate.

Registration is open via the following link.
