I have been actively engaged in synthesizing and designing MXenes thin films using bottom-up approaches. I specialized in the deposition of MXenes using a bottom-up approach via sputtering. This process involved the meticulous preparation of elemental targets, including transition metals and carbon or nitrogen sources. By utilizing high-energy particle bombardment in a vacuum chamber, I facilitated the ejection of atoms from the target surface, which then deposited onto a substrate to form a thin film of MXene material. Post-deposition treatments, such as annealing, were employed to enhance the crystallinity and properties of the films. This method allowed for precise control over film thickness and composition, making it highly suitable for applications in electronics, energy storage, and , I have been working on the fabrication and characterization of metal oxide-based gas sensors by employing DC and RF magnetron sputtering techniques. My experience extends to wor
