Research Projects

In this project, the effect of dimensionality of these nanometer-range materials will be studied. Solution processed syntheses of these 2D nanomaterials are challenging. Colloidal syntheses in liquid media has emerged as an efficient, convenient, and highly reproducible method for producing nanocrystals with precise control over their size, shape, and surface properties. This solution-based synthesis approach enables the formation of nanocrystals with uniform and tunable dimensions, which can be scaled across a range of sizes by adjusting parameters like temperature, concentration, and reaction time. Additionally, nanocrystals synthesized in liquid media are readily dispersible in both organic and aqueous solvents, making them adaptable for applications in optoelectronics. Different synthetic stimuli driven structural transformation can provide new 2D layered materials with different shape and composition. Cation or anion exchange mediated transformation enable us to study a variety of nanomaterials. Characterization techniques such as transmission electron microscopy and spectroscopic characterization will be used to characterize these materials. Additionally, the photovoltaic device fabricated using these nanomaterials will be undertaken. Advances in rational design and understanding of heterostructured 2D layered nanocrystals are opening up exciting pathways for developing enhanced material properties and multifunctional devices. By engineering heterostructures—combinations of two or more distinct 2D materials stacked or interfaced at the nanoscale—it’s possible to create nanocrystals that exhibit synergistic properties, overcoming limitations seen in individual components. This approach promises to unlock unprecedented performance in a range of applications, particularly in optoelectronics, energy storage, catalysis, and sensing. During this period of research, I can benefit in many ways. There are several research group nationally and internationally working in synthesis strategies for colloidal nanomaterials, which would be very beneficial for me to develop different synthetic approaches for synthesizing a variety of 2D colloidal nanomaterials. Beyond, I can collaborate with them for developing devices to study the photo-induced electrical properties of 2D materials. Since during my doctoral studied I have also synthesized different heterostructures using colloidal synthesis route which definitely helped me to fabricate new emerging materials which will be beneficial for executing this project. This scientific project will significantly contribute to the field of nanoscience and nanotechnology.
