Microscopic Gardening: Tiny Blossoms of Silicon by Vivek Garg has been voted the Australian National Fabrication Facility- Victoria Node (ANFF-VIC) Image of the Year 2018 by Melbourne Centre for Nano-fabrication (MCN).
The image shows a scanning electron micrograph (false-color) of Silicon (Si) nanoflowers, created using MCN’s Focused Ion Beam (FIB) in conjunction with wet chemical etching.
Vivek and his colleagues are investigating fabrication of 3D freeform structures of Si, such as these nanoflowers, due to their unique optical properties. Such structures can be engineered for multicolor generation through selective absorption of light and have tremendous potential for future optics offering unique opportunities for optical security, polarimetry, spectral imaging applications etc.
“The bulk structuration of Si substrate, based on the ion implantation design and area, allows fabrication of exotic functional and 3D micro/nanostructures on Si substrate exhibiting unique optical properties for applications in nanophotonics and physical sciences,” Vivek explained.
Vivek is a PhD candidate with the IITB-Monash Research Academy, a collaboration between IIT Bombay, India and Monash University, Australia and recipient of Tata Consultancy Services (TCS) Research Scholarship. He is working with Dr. Rakesh Mote, Department of Mechanical Engineering, IIT Bombay, India and Dr. Jing Fu, Department of Mechanical and Aerospace Engineering, Monash University, Australia on fabrication and controlled manipulation of freeform 3D micro/nanostructures with ion beams. This work is a part of his thesis project FIB nanofabrication and its application in creating novel nanostructures for diverse applications such as anti-reflection, color filters, sensors etc. to name a few.
