Welcome to my Webpage
I am a Postdoctoral Scientist at CNR Istituto Nanoscienze, Pisa, Italy and a Blogger at #NewWaveParticle, INDIA.................
My research interest is in design and fabrication of different nano structures and electrodes using the GLAD technique for the application of light trapping, gas sensing/ nano nose, SERS substrate, multifunctional coating and magnetic memory devices. Glancing Angle Deposition (GLAD) is a PVD technique which uses both top-down and bottom-up approach in a single go. The heart of this technique is to control substrate tilt angle and substrate rotation simultaneously and hence to give the flexibility to nurture the structure.The resultant structures coming out of this technique are usually porous, graded, anisotropic, and have a high surface to volume ratio. Further, for desired properties to incorporate the structure into an application, we do pre-deposition and post-deposition treatment using lithography, reactive ion etching, annealing, etc.
Research Interest
Currently, I am involved in fabrication of vertical organic field effect transistors (VOFETs) to modulate the switching speed and to develop neuromorphic devices. I have been an expert on fabrication of complex nanostructures using glancing angle deposition (GLAD) technique for the applications in the field of Structural colours, Superhydrophilic surfaces, Self-cleaning surfaces, Hydrophobic SERS substrates, and Gas sensors.
