innovation for industry
News | Micro-nanoelectronics
Ludwig Rotsen wanted to draw inspiration from life to create advanced nanotechnologies, and he has done an excellent job addressing his goal, confirming CEA-Leti's focus on always reinventing innovation based on available resources and on demand.

After completing of the first part of his thesis in Montpellier, France, Ludwig Rotsen joined CEA-Leti to work on DNA origami for use in lithography, in collaboration with the CNRS.
The versatility and addressability of DNA are unprecedented, making it possible to broaden our catalog of 2D networks and to envision increasingly specific uses that will require nanostructures. This high addressability and the limited quantity of lithographic material mean that it is possible to generate countless structures in a relatively short timeframe (in the order of several weeks).
Thanks to the new process for depositing DNA nanostructures on silicon dioxide, Ludwig controls every 2D network interaction, and his work will enable great strides in the field of quantum computers.
Ludwig notes "𝑺𝒊𝒏𝒄𝒆 𝑰 𝒂𝒎 𝒘𝒐𝒓𝒌𝒊𝒏𝒈 𝒐𝒏 𝒂 𝒎𝒖𝒍𝒕𝒊𝒅𝒊𝒔𝒄𝒊𝒑𝒍𝒊𝒏𝒂𝒓𝒚 𝒔𝒖𝒃𝒋𝒆𝒄𝒕, 𝑰 𝒘𝒆𝒂𝒓 𝒕𝒘𝒐 𝒉𝒂𝒕𝒔—𝒕𝒉𝒂𝒕 𝒐𝒇 𝒂 𝒑𝒉𝒚𝒔𝒊𝒄𝒊𝒔𝒕 𝒂𝒏𝒅 𝒕𝒉𝒂𝒕 𝒐𝒇 𝒂 𝒄𝒉𝒆𝒎𝒊𝒔𝒕. 𝑰 𝒄𝒂𝒏'𝒕 𝒂𝒍𝒘𝒂𝒚𝒔 𝒈𝒊𝒗𝒆 𝒂𝒅𝒗𝒊𝒄𝒆 𝒐𝒏 𝒗𝒆𝒓𝒚 𝒔𝒑𝒆𝒄𝒊𝒂𝒍𝒊𝒛𝒆𝒅 𝒕𝒐𝒑𝒊𝒄𝒔 𝒊𝒏 𝒆𝒊𝒕𝒉𝒆𝒓 𝒐𝒇 𝒕𝒉𝒐𝒔𝒆 𝒇𝒊𝒆𝒍𝒅𝒔, 𝒃𝒖𝒕 𝑰 𝒂𝒍𝒘𝒂𝒚𝒔 𝒉𝒂𝒗𝒆 𝒂𝒏 𝒐𝒑𝒑𝒐𝒓𝒕𝒖𝒏𝒊𝒕𝒚 𝒕𝒐 𝒍𝒆𝒂𝒓𝒏 𝒔𝒐𝒎𝒆𝒕𝒉𝒊𝒏𝒈 𝒏𝒆𝒘!"
Both his greatest challenge and what he has most enjoyed has been participating in a project for two organizations that have different approaches. Working at CEA-Leti has taught him to better understand real-work applications for his thesis, along with issues around the transfer of his innovation to the industry market.
To close, his experience reminds us that sometimes, reorganizing what exists is a way of finding innovative solutions for tomorrow's technologies.
