Material scientist, solar energy & EM wave manipulation. Expert in advanced semiconductor Nano/Micro fabrication.

Profile Summary

Over the years I have gained huge experience in manipulation of electromagnetic waves using metasurfaces; from designing and simulation to fabrication of prototypes and their spectral analyses. Our projects focus on the investigation of novel and compatible material choices with unique dielectric properties for desired passive and active responses. Myself and team members have work extensively on projects that manipulate the optoelectronic properties of oxides, metal thin films, 2D materials/hetero-structures, by doping with impurities using pulse laser, ion implantation or other chemical and physical techniques. In the past 5 years, I have employ advanced semiconductor nano/micro (CMOS) fabrication techniques in state-of-the-art facilities to realize components, devices and prototypes for application as sensors in the health, agriculture and image acquisition applications, or as antennas for communication. These techniques include but not limited to, Electron beam deposition, DC/pulsed DC/RF magnetron sputtering, Inductive coupled plasma deep reactive ion (ICP DRIE) and wet etching, Maskless photolithography (MLA150/300), plasma enhanced chemical vapour deposition (PECVD), Electron beam lithography (EBL), processing of low loss thin polymer films of all thickness between 5 to 150 microns thick. Patterning of metallic resonators on ultra thin polymer films (free standing) for research and industrial applications. Fabrication of multilayer (up to 3 layers) metasurface devices for research purposes. Other expertise include sol-gel synthesis of semiconductor oxides for application in light harvesting. Python programming for machine learning for antenna designs. Advanced mask designing using specialized software such as Klayout, Autocad, L-Edit etc. You can also reach me for collaboration.
