Abstract:We describe an approach for preparing systems of semiconductor quantum wires (QWRs) or quantum dots (QDs) with perfect site control combined with good spectral control and high optical emission efficiency, for applications in deterministic quantum photonics. The approach is based on organometallic vapour phase epitaxy on patterned, nonplanar substrates, through which the QWRs/QDs are self-formed in V-groove channels or pyramidal pits. Excellent uniformity (inhomogeneous broadening as low as ~1 meV), tailored h… Show more
