Zigzag antimonene nanoribbons for nanoscaled optical devices

In the present work, the electronic and optical properties of zigzag antimonene nanoribbons are investigated using density functional theory (DFT) calculations. The electronic properties of nanoribbons such as bad gap size and projected density of states are calculated. In the case of optical properties, the real and imaginary parts of the dielectric function and absorption coefficient are obtained for different values of nanoribbons' width. Based on the simulation results of the present work, antimonene nanoribbons are suitable for absorption of the photons with wavelengths between 384 nm to 568 nm.
