Figure

Figure 7 shows an XRD scan of this film revealing the suc- suc-cessful growth of the cubic rocksalt structure with a lattice constant of 5.863(7) A ˚ , which is close to the bulk LaS bulk value of a ¼ 5.857(2) A ˚
Figure 19 shows there are two LaS layers on the InP sub- sub-strate, and the thicknesses of LaS(1) and LaS(2) are 52 and 121 nm, respectively
