Grafeno torcido revela novo método de controle de supercondutividade

Pesquisadores descobriram uma maneira de ligar e desligar a supercondutividade em grafeno de bicamada torcido ajustando seu ambiente. A descoberta desafia teorias convencionais e pode impulsionar a eletrônica com eficiência energética. O trabalho foi publicado na Nature Physics.

Uma equipe liderada por Chun Ning (Jeanie) Lau na Universidade Estadual de Ohio combinou grafeno de bicamada torcido com titanato de estrôncio. Essa configuração permitiu ajustar como os elétrons interagem e controlar a supercondutividade alterando o ambiente do material. A abordagem difere dos métodos tradicionais que focam na redução da repulsão eletrônica dentro do próprio material.
