Figure 4

A comparison of the band structures near the K point for (a) BiH, (b) BiF and (c) SbF monolayers calculated using DFT and LEEH methods. The solid gray and solid red lines denote the data calculated using DFT theory without SOC and with SOC, respectively. The dashed blue and dashed green lines represent the data calculated using the LEEH method with SOC and without SOC, respectively. The Fermi level is set to zero.
