Tiny 'whirlpools' discovered in atom-thin semiconductor‎

Monash University-led researchers have directly imaged tiny swirling structures inside an atomically thin semiconductor, opening new possibilities for future low-energy electronic technologies. Published in Science Advances, the study reveals structures known as merons and antimerons, nanoscale "whirlpools" of electrical polarization, in twisted layers of the semiconductor tungsten diselenide (WSe₂).
