Structural and characterization of the MQW NW array. (a) Schematics of the WZ based InP NW, facet-rotated InP core-shell NW, and InGaAs/InP MQW NW, respectively. (b) 30° tilted SEM image of the NW array grown on InP(111)A substrate. (c) STEM-HAADF image of the lateral cross-section of an InGaAs/InP QW NW. The dashed blue line indicates the expected position of WZ InP NW core which is covered with the 30° rotated InP shell and MQW structure. (d) STEM-HAADF image taken along [112] zone axis from the vertical cross-section of NW top segment.
