Spin splitting and electric field modulated electron-hole pockets in antimonene nanoribbons

One-dimensional nanoribbons: A platform for probing exotic magnetoresistance Electrically-tunable electron-hole pockets could make antimonene nanoribbons a platform for probing unusual magnetoresistance effects. Some material changes their resistance when a magnetic field is applied—an effect known...
