Abstract
The honeycomb lattice of β
12-borophene has two types of triplet and Dirac fermions with different momenta. The coexistence of these fermions engenders anisotropic optical responses. The main goal of this work is to engineer the effect of electrostatic gating on such responses. We numerically calculate an effective optical conductivity tensor to address the effect of gate voltage on the blueshift (along the x-direction) and redshift (along the y-direction) spectra through multi-interband transitions. We also find a blueshift spectrum for the Hall conductivity. Further, we investigate the role of partial optical interband transitions on the total effective transitions. The findings here can be considered for practical optoelectronic applications.
