Isolating single selected quantum dots using cryogenic photolithography

Abstract
We propose and demonstrate a technique combining micro-photoluminescence imaging with scanning photolithography at Cryogenic temperatures for creating photoresist masks at designated locations relative to single selected self-assembled quantum dots. The technique is demonstrated by producing a photoresist mask on top of a single selected InP quantum dot imbedded in GaInP. A mesa containing the quantum dot is then created by wet chemical etching. The combination of micro-photoluminescence and scanning photolithography relies on the use of two different lasers with a micro-photoluminescence setup, each laser having different power, focusing and wavelength. The resulting structure enables many experiments and applications in the emerging... (More)
