Vibrationally Promoted Electronic Resonance Microscopy for Structural-Electronic Coupling Studies in Single Quantum Dots

In this proposal, I aim to investigate the mechanisms of structural-electronic coupling at both microscopic and nanoscopic levels and their effects on the optoelectronic properties of hybrid organicinorganic perovskites (HOIPs) single quantum dots. By leveraging my expertise in the photophysics of HOIPs nanocrystals, my experience in developing and utilizing vibrationally selective microscopy, and my host research group's proficiency in applying advanced vibrational-electronic techniques to study operando optoelectronic devices, we will push beyond the current state-of-the-art. We will develop a novel nonlinear spectroscopic microscopy technique with high temporal and spatial resolution. This approach will not only uncover the intrinsic mechanisms of vibronic coupling that affect optoelectronic properties in single quantum dotsmechanisms often hidden in traditional ensemble measurementsbut also provide a unique method for studying how vibrational coupling influences quantum phenomena, such as single-photon emission. Our findings will offer mechanistic insights that can drive the development of new nanomaterials for photovoltaics, lighting applications, and single-photon sources.
