Outline
Project description: CuInZnS3 quantum dots (CIZS QDs) is a non-toxic and phosphide free material which has a significant potential to be used in wearable PVs and indoor PVs [1,2]. However, due to its emission properties apparently dominated by defects, its carrier dynamics are more complicated than binary metal chalcogenides and are not yet well understood. For instance, the origin of the light emission broadening is still unclear, with mechanism of poly-disperse size distribution and sub-bandgap states. The investigation of carrier dynamics in the ensemble, and within single dot emission spectroscopy not only can help us to understand the challenge of PL spectra broadening but also can provide deep insight regarding the band structures and carrier dynamics within this quaternary compound semiconductor QDs.
In this project, the student will be trained in synthesising CIZS QDs through continuous flow or heterogeneous [3] synthesis approach which are considered as the most promising techniques for fabrication large-scale colloidal QDs. Moreover, we will use the state-of-the-art laser micro-spectroscopy and ultrafast optical spectroscopy setups [4] to investigate the emission line-shape [5] and carrier dynamics of ensembles and single dots.
The student will also develop experimental skills and knowledge in optics & lasers by using femtosecond lasers systems and a complex optical setup, develop skills in programming by adapting the software to control the experiment, and perform data analysis and modelling using the knowledge on the physical processes involved.
