FEM simulation results for a P content of 20%, a segment thickness of 43 nm and a shell thickness for the inner and the outer shell of 1 nm and 2.5 nm, respectively. ∊yy is the strain in the lateral direction and ∊zz is that in the growth direction, given in %. The outer diameter of the simulated NW is 175 nm and the NW's length is 700 nm. Note that the axes are not on the same scale. Moreover, the WZ/ZB distribution function used in this simulation is illustrated on the left-hand side. |
