A nanowire quantum dot integrated with a five-gate electrostatic device enables three-dimensional electric-field control of charge configuration and symmetry. Photoluminescence measurements show Stark shifts up to ~6.9 meV and gate-dependent excitonic redistribution, revealing complex local electric-field effects.
