Phys. Chem. Chem. Phys., 2020, 22,9685-9692
DOI: 10.1039/D0CP00729C, Paper

Yifan Liu, Yuanfeng Xu, Yanju Ji, Hao Zhang
The bandgaps for monolayers Bi₂Se₃, Bi₂Se₂Te and Bi₂SeTe₂ decrease under moderate strains ranging from −4% to 10%, and the predicted electron mobilities are high, reaching 2708 cm² V⁻¹ s⁻¹ for Bi₂SeTe₂.
