Research Theme 2: Heterointegration

Research Theme 2 (RT-2) includes teams that are taking the new materials synthesized in RT-1 and using sophisticated equipment and techniques to place and pattern them with exquisite levels of precision, enabling the building of new device architectures.

The different approaches being brought together in RT-2 are enabling the scalable integration of colloidal quantum dots into device structures. If we are to build new optoelectronic technologies and applications, we need to have reliable, scalable, and accurate techniques to integrate the new materials made by RT-1 into existing or new electronic device structures. This enables architectures for linear, non-linear, and quantum optoelectronic devices.

Once these new materials have been integrated into device architectures, members of the RT-2 team investigate how these new materials interact with the surroundings, exploring the behavior of the excitons, spins, and charges within and across the interfaces of the new materials. This can help the investigators better understand and optimize the materials.

RT-2’s collaborations with RT-1 inform the design new materials that are optimized for accurate placement. RT-2’s collaborations with RT-3 inform the properties of the device and develop new placements and patterns of materials based on their properties.
