The Effects of Disorder and Dimensionality on the Environment Assisted Quantum Transport of Excitons in Quantum Dot Superlattices

<p dir="ltr">Understanding the fundamentals of exciton transport is essential to better inform the design and application of quantum dot superlattices (QDSLs) in light harvesting systems. Exciton transport is subject to a complex energy landscape where the forces that govern delocalization distances are a result of the wavefunction of the exciton and environmental incoherent forces. By changing the temperature of the surroundings, the exciton will transition between two motivating transport methods: a wave-like ballistic method of diffusion and a particle-like Brownian method of diffusion. Mixing these regimes of transport demonstrates how ENAQT can motivate a maximum amount of transport at an intermediate temperature. This thesis examines measurements made on CsPbBr₃ QDSLs, demonstrating the difference between these two transport mechanisms and the role of dimensionality on the ability of excitons to transport.</p>
