Research Theme 1: Precision Synthesis

Research Theme 1 (RT-1) includes the teams that are developing new chemical reactions to synthesize the building blocks that make up the next generation of optoelectronic devices.

Transforming optical technologies with colloidal quantum dots begins with synthesizing novel materials that have superior performance and can be easily handled and incorporated into devices and applications. Members of RT-1 are advancing the fundamental science underpinning colloidal semiconductors.

Combining multi-level theory and experimentation the team engaged in RT-1 are innovating techniques to control the precision synthesis of colloidal materials and their surfaces to produce quantum dots with advanced combinations of color purity (linewidth), stability, brightness, and processability from ensembles down to single dot precision.

RT-1’s collaboration with RT-2 revolves around the design of new materials that enable accurate and reliable placement of the new materials in device architectures. RT-1’s collaboration with RT-3 uses the feedback from device engineers to innovate on new materials that have properties desired in new device structures.
