Project
Colloidal Quantum Dot Based Photodiodes for Multispectral Sensing and Imaging in Short-Wave Infrared
The purpose of this PhD is to research devices for scaled multi-spectral thin-film imagers. The thin-film semiconductors are deposited from either solution (polymer semiconductors, or colloidal quantum dots) or by evaporation (stacks of organic small molecules). The full stack will be defined by the optical and electrical properties of each layer, as well as the process limitations inherent to stacking of thin films. This PhD therefore has two important pillars: 1) optical and electrical simulations of the full layer structure, and 2) process development to realize complex stacks with high performance for the relevant performance parameters of photo-detection. The PhD student will be involved in the entire fabrication cycle (design, processing and characterization) performed in the state-of-the-art facilities including imec's cleanroom and dedicated thin-film labs.
