This is a past event.

Dhara Trivedi from Clarkson University will be presenting at this week's Physics Colloquium. The seminar will be presented in person at 4 PM, Thursday, November 2 in Fisher 139.

ABSTRACT:

Two-dimensional perovskites (2DPKs) are unmatched in their ability to realize finely tunable optoelectronic properties through simple changes such as pressure modification, variable layered arrangements, and confinement effects associated with an electronic decoupling of adjacent inorganic layers. This flexibility has led to successful application of 2DPKs as efficient light emitters, photodetectors, and hybrid photovoltaic (PV) and thermoelectric (TE) materials. An atomistic description obtained using ab initio studies provides a unique and comprehensive understanding of the band structure, optoelectronic performance of the 2DPK, and in turn influence of these parameters on it. Additionally, utilizing Boltzmann transport equations (BTEs) on the obtained structures provides insights into the thermoelectric performance of them. This talk will highlight some of our recent works for understanding the influence of various parameters on the performance of 2DPKs as a hybrid PV-TE material for perovskite-based solar energy-harvesting device.

BIO:

Dhara Trivedi is currently an Assistant Professor in the Department of Physics at Clarkson University. Her group aims to understand the electronic processes in the condensed phases. Using tools from electronic structure theory and molecular dynamics, they perform a comprehensive theoretical and computational investigation to study charge and energy transfer, electronic relaxation, and multilinear spectroscopy in novel materials, such as perovskites, metal-organic frameworks, and plasmonic nanostructures. Trivedi earned her PhD in Physics from the University of Rochester in 2015. Under the guidance of Prof. Oleg V. Prezhdo, her PhD research was in nonadiabatic molecular dynamics in nanoscale system. In the period of 2015-2018, she worked as a postdoctoral fellow with Prof. George Schatz at Northwestern University. During this time, she worked on applications of plasmonics properties of nanoscale systems. In 2018, she joined Clarkson University.
