Semiconductor quantum dots (QDs) form a promising platform for application in lighting devices such as LEDs or lasers. For this reason, in this project the student will investigate the light-matter interaction in semiconductors at the strong quantum confinement regime, using ultrafast spectroscopy techniques, and explore optical gain in nanomaterials excited by ultrafast pulses (50-80 fs). The candidate will learn to deposit quantum dots in thin films through the spin-coating process. Finally, the candidate will study optical gain indifferent types of nanomaterials, correlating the threshold to their electronic properties.
