Description
Epitaxially grown self-assembled semiconductor quantum dots (QDs) offer atom-like optical properties, making them ideal for single photon sources in quantum technologies. Selecting a QD with specific characteristics is crucial for noise-free, indistinguishable photons. We developed a screening protocol to identify the best QD from multitude of simultaneously grown dots. Our study revealed anisotropic elemental composition within single QDs, challenging existing models assuming lateral azimuthal symmetry. Additionally, we observed a progressive rotation of in-plane lattices, forming naturally occurring chiral structures. This groundbreaking discovery of nanoscale chirality within zero-dimensional QDs has profound implications for revolutionizing quantum technology.
