Study of hot carrier dynamics and relaxation in metal halide perovskites
(2023-05)
Metal halide perovskites are a promising class of solution-based semiconductors
with significant potential for optoelectronic devices, including hot carrier solar cells
that are proposed to achieve higher efficiency than ...
High-precision measurements of alkanethiol self-assembled monolayer structure with scanning tunneling microscopy
(2020)
This thesis describes a measurement methodology and set of tools for measuring scanning tunneling microscope images of crystals at picometer length scales. We use the crystal structure present in high-quality scanning ...
Intervalley Scattering in III-V Heterostructures and its Application to Valley Photovoltaic Hot Carrier Solar Cells
(2022-12-16)
The efficiency limit of 33% for a single gap solar cell is not fundamental. Mitigation of thermalization losses which occur when high energy ‘hot’ carriers are only extracted at the same energy as low energy carriers is a ...
