Quantum dots are nano-scale structures grown by self-assembled epitaxial methods. In this project, intermixing of quantum dots, which is a novel technology to modify the opto-electronic properties of the dots will be studied using ion implantation and subsequent annealing. Optimised growth, implantation and annealing conditions will be used to grow and tune the detection wavelength of the infrared photodetectors using intersubband transition. This will allow us to fabricate multi-wavelength infrared photodetectors for high performance infrared imaging system. This project involves an exciting combination of fundamental physics and device technology.

量子点是通过自组装外延方法生长的纳米级结构。在这个项目中，量子点的混合，这是一种新的技术，以修改点的光电性能将使用离子注入和随后的退火进行研究。优化的生长、注入和退火条件将用于利用子带间跃迁生长和调谐红外光电探测器的检测波长。这将使我们能够制作多波长红外光电探测器的高性能红外成像系统。该项目涉及基础物理和设备技术的令人兴奋的结合。
