I currently work as a Post-Doctoral Research Associate in the School of Physics and Astronomy at Cardiff University in the United Kingdom. Specifically, I am affiliated with the research group led by Prof. Oliver Williams. My primary focus of research lies in exploring the potential of diamond as a material for various applications. In particular, I am highly interested in utilising nanocrystalline diamond grown on non-diamond substrates. Although nanocrystalline diamond may not possess the same superior qualities as single crystal diamond, it offers advantages such as a larger surface area, scalability of devices, and cost-effectiveness.

 

One significant challenge associated with lab-grown nanodiamond films is their inherent surface roughness. However, we have successfully addressed this issue by developing a polishing technique that can achieve sub-nanometer surface roughness. Over the years, the Cardiff Diamond Foundry has published several papers focusing on the polishing of thin film diamond. For a comprehensive list of publications related to diamond polishing, please refer to this link. Additionally, at the Cardiff Diamond Foundry, we have designed a low-cost chemical vapour deposition (CVD) reactor, inspired by the NIRIM (National Institute for Research in Inorganic Materials) type, which facilitates diamond growth. You can find the complete design of this reactor on this wikiversity page.

 

Prior to Cardiff university, I worked at Institut Neel in Grenoble, France, in the group of Prof. Christopher Bauerle and Prof. Laurent Saminadayar. During my time there, I contributed to a project involving superconducting boron-doped diamond. Our efforts resulted in the realisation of quantum devices capable of functioning in magnetic fields as high as 4T. For a comprehensive list of articles on boron-doped diamond devices published based on my work at Grenoble, please follow this link.

 

My doctoral studies was carried out under the guidance of Prof. R. C. Budhani in the Department of Physics at IIT Kanpur. Throughout my Ph.D., I extensively researched the interaction between superconductors and ferromagnets, as well as investigated various galvanomagnetic properties of double-exchange perovskites such as LSMO.
