ABSTRACT

According to quantum communication and quantum computing applications, room temperature, electrical injected single photon sources display important scientific significance and practical value. Up to the present, room temperature, electrical injected single photon sources have not been reported. We will etch photonic crystal holes into the electrical injected quantum well light-emitting materials, control the depth of the hole to reach the quantum well layer and introduce colloidal quantum dots in the photonic crystal holes. By controlling the concentration of quantum dots and making the electrode, the energy will transfer efficiency from quantum well light-emitting materials to quantum dots under the principle of Forster resonant energy transfer (FRET). Furthermore, we will research on emitting characteristics with high efficiency, room temperature electric injected single photon sources by reducing the concentration of quantum dots. Focusing on the interaction principle between quantum wells and quantum dots, using micro-processing technology, we will design, fabricate and detect electrical injected single photon sources, which will work at room temperature. This study is very innovative in working principle, fabrication technology and prototype devices. The implementation and completion of this project will m More... »
