Quantum dot lab: an online platform for quantum dot simulations

Self-assembled quantum dots have improved the performance of many optoelectronic devices such as infrared photodetectors and intermediate band solar cells [1], [2]. They offer the ability to tune device parameters by carefully adjusting device dimensions. Designing an optimal quantum dot for a specific purpose requires intensive simulation beforehand to get an idea on the effect of various materials and dimensions on optical properties of the dot. Quantum Dot Lab deployed on nanoHUB [3] provides such a simulation platform for the research community. The tool has the ability to simulate quantum dots ranging from simplistic particle in a box in effective mass approximation (EMA) till selfassembled quantum dots in 10-band sp3d5s* tight binding (TB) basis.
