Abstract
Photoluminescence measurements in magnetic fields up to 16T are reported from single InAs∕InP quantum dots nucleated at the apex of individual InP pyramidal nanotemplates. Clear Zeeman splitting and diamagnetic shifts of the s-shell exciton peak are observed and are correlated with the quantum-dot dimension. This behavior is interpreted in terms of a template-controlled quantum-dot diameter and is corroborated by the observed diamagnetic shifts.Keywords
