Growth and Intermixing of Quantum Dots for Multi Wavelength Infrared Photodetectors

    Project: Research

    Project Details

    Description

    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.
