Predicting the characteristics of a C₂B₆ monolayer with ultrahigh carrier mobility.

ABSTRACT: Two-dimensional materials have excellent electronic and optical properties, suggesting absolute advantages in nanodevices. In this work, a new two-dimensional material with a puckered structure, a C₂B₆ monolayer, is proposed. The material presents dynamic and thermal stability calculated by first-principle simulations. Interestingly, the C₂B₆ monolayer possesses semiconductor behavior with an ultra-narrow bandgap of approximately 0.671 eV by HSE06 functional. Meanwhile, the hole in the C₂B₆ monolayer shows ultrahigh mobility at approximately 6,342 cm²⋅V^-1⋅s^-1 in decent transport directions, which is larger than traditional transition metal dichalcogenides materials. More importantly, the pron
