Moire Quantum Dot Array Polaritons for Ultra-Low Energy Optoelectronics
Abstract
Quantum dots with discrete energy levels hold the key to ultra-low energy and high efficiency optoelectronic information processing at the physical limit, if not limited by inhomogeneity. Yet large dot-to-dot inhomogeneity of conventional types of quantum dots continue to severely limit their applications after decades of research. The recent discovery of moiré superlattices formed in van der Waals material heterostructures has opened up the opportunity to realize naturally-formed, uniform quantum dots arrays that can collectively couple with light. Building on the preliminary validation of this concept and the development of critical techniques for moiré system in the PIs labs, we aim to perform systematic studies of the new moiré quantum dot array polariton system, develop the methodology to characterize the system and to control its key properties, understand and optimize its main figures of merits for ultralow energy photonics, and demonstrate proof-of-concept ultra-low energy and high efficiency switching and lasing. The work will lay the ground for a new type of high-performance optoelectronic platform with heterogeneous integration with silicon. The project will also foster collaborations and scientific exchanges between the US and Taiwan.
