Main research activity: The Laboratory of Quantum Materials and Nanophotonics specializes in the cutting-edge exploration of semiconductor quantum dots; and optical properties, focusing on how these nanoscopic particles interact with light. This facility is renowned for its comprehensive study of various quantum dot types, with a particular emphasis on those with non-trivial geometries. These unique shapes open up new avenues for manipulating electronic and optical properties, paving the way for groundbreaking advancements in quantum computing, photovoltaics, and bioimaging. By harnessing the peculiarities of these quantum dots, the laboratory aims to unlock novel photonic phenomena and applications.
Our research delves into the intricate interactions between semiconductor quantum dots and various types of liquid crystal molecules with the help of an atomistic approach like Density Function Theory (DFT), aiming to understand the complex interplay at the nanoscale. By investigating these interactions, we seek to unravel the mechanisms governing the alignment and phase behavior of quantum dots within liquid crystal matrices. Utilizing advanced computational and experimental methods, we calculate the free energy of the system, providing insights into its stability and thermodynamic properties. Additionally, we assess the absorbance characteristics of these composite systems, exploring their potential for novel optoelectronic applications and dynamic display technologies.
The experimental arm of our research is dedicated to the pioneering development of quantum dot liquid crystal composites (QDLCs). In this venture, we combine the unique spectral and wave function properties of QDs with the high responsiveness of liquid crystals to external stimuli. Our experimental efforts are geared towards harnessing and enhancing the electro-optical, magnetic, and thermal properties of QDLCs.
