Abstract:

Materials chemists have rapidly advanced the synthesis, and the physical understanding, of a new class of semiconductors based on colloidal quantum dots. These materials are attractive for their highly scalable synthesis, their ready manufacturing from the solution phase, and their wide-ranging spectral tunability through the quantum size effect.

I will discuss advances in exploiting this class of materials into high-performance devices. I will focus on photodetection, relevant to imaging (both visible and infrared), and also photovoltaics, relevant to solar energy harvesting.

I will discuss the deployment of interdisciplinary engineering physics' advances in device performance, materials chemistry, electronic spectroscopies, and materials and device modeling - that have enabled rapid progress in the field, and will discuss its prospects.
