Figure 6
The strain in and around the InAs1–xPx region is shown for simulations with different shell arrangements, indicated in cuts through the wire, shown in (a), for a NW without shells (1) and for a NW with two different shell dimensions (2, 3); in (2) an inner-shell thickness of 1 nm and outer-shell thickness of 2.5 nm and in (3) an inner-shell thickness of 4 nm and outer-shell thickness of 4 nm. For a better visualization the core region and the shell region of the NW are plotted separately, as depicted in (a) with black and red boxes. (b) ∊yy and ∊zz in the core region, i.e. in the black boxes. (c) ∊yy and ∊zz in the shell region, i.e. in the red boxes. The given strain values are always relative to the according relaxed ZB and WZ, InAs and InAs1–xPx lattice parameters.
