Project description
Harnessing a unique partnership between photons and phonons in perovskites
Controlling and manipulating the interactions between light and matter opens the door to novel applications in numerous areas including lighting and illumination, medical imaging, solar cells, sensors and telecommunications. Adding vibrational effects or structural deformations in addition to conventional emission, reflection and transmission processes is an exciting new frontier of exploration. With the support of the Marie Skłodowska-Curie Actions programme, the PeroVIB project is investigating the potential of modulating the electronic dynamics in hybrid perovskites using structural deformations and vibrations induced by coupling with photoexcited charge carriers. The technique will be explored with real functional devices as well, leading to structural design rules to achieve desired optoelectronic functions.
Objective
"Owing to the “soft” nature of perovskite lattice, structural deformations (vibrations) play a crucial role in modulating the electronic dynamics of perovskites. In fact, one may engineer the key optoelectronic properties of this class of materials by tuning the coupling strength between photoexcited charge carriers and lattice phonons. Experimental realization of such vibronic coupling in the compositional space of perovskites remains so far unexplored. Herein through this project, I aim to identify the crucial vibrational modes of hybrid perovskites (of various compositions and dimensions) that influence the electronic dynamics and charge transport in real electronic devices of them. To address this fundamental problem, I plan to develop double-resonant excitation (infrared pre-excitation prior to electronic excitation) based ""Vibrationally Promoted Electronic Resonance"" spectroscopic technique that will give a direct access to monitor the vibrational dynamics of organic and inorganic sub-lattice in the electronically excited state of the hybrid perovskites. This technique is specifically proposed here for probing the vibronic coupling of these soft materials with high mode-selectivity. We will further explore pump-push photocurrent spectroscopy on real functional electronic devices of those perovskites to identify the role of structural fluctuations in modulating the charge transport efficiency. This unique hybrid spectroscopic approach will provide wealth of information from fundamental structural dynamics to device performance; which will enable us to develop design rules of structure-function relationship to maximize the efficiency of perovskite devices. This research program will not only provide an opportunity to enhance my research skills, which in turn will facilitate to launch my independent research group in future but also outcome of the project will advance the current research field by replacing the current assumptions with the experimental findings."
