Description

The usability and tunability of the essential InP–InGaAs material combination in nanowire-based quantum wells (QWs) are assessed. The wurtzite phase core-multi-shell InP–InGaAs–InP nanowire QWs are characterised using cross-section transmission electron microscopy and photoluminescence measurements. The InP–InGaAs direct interface is found to be sharp while the InGaAs–InP inverted interface is more diffused, in agreement with their planar counterpart. Bright emission is observed from the single...[Show more]
