Revolutionary Nanopatterning Technique Developed

In May 2024, Indian Institute of Technology Guwahati and Columbia University scientists achieved a groundbreaking advancement in nanopatterning, utilizing a simple tabletop infrared (IR) laser.

Innovative Nanopatterning Method

• Nanopatterning involves creating intricate patterns on materials at the nanometre scale, vital for various advanced devices like light detectors, solar cells, lasers, and LEDs.
• Traditional nanoscale patterning methods necessitate specialized equipment and infrastructure, posing accessibility and cost challenges.

Optical Driving: A Novel Approach

• The team adopted a less complex technique called "optical driving," exploiting the resonance frequency principle in materials to overcome these challenges.
• By employing the "unzipping" technique, they cleaved hexagonal boron nitride ....
