Preparation of Pyramid-Shaped Substrate for Site-Controlled Growth Quantum Dots
In the ideal situation, a single photon is produced by the emission of quantum dot single photon source. A quantum dot single photon emission device is achieved when we combine the self-organized growth method with optical microcavity structure on patterned substrate. When we adopt a pyramid-shaped substrate to prepare quantum dots, quantum dot growth with a high degree site-controlled is achieved, and single photon source quantum dots are easy to prepare and isolate. The problem of multiple quantum dots occupying the same position can be solved when we use the pyramid-shaped substrate, and the quantum dot preparation in the pyramid-shaped substrate is beneficial to the photon emission and collection.
