Personal profile

Krishna Nama received his B.E. in Electronics and Communication from Visvesvaraya Technological University, Bangalore, India, (2010) and MSc in Microelectronics and Nanotechnology from De Montfort University (DMU), Leicester, (2012).  He is currently pursuing his PhD funded by De Montfort University, researching about advanced nanomaterials and techniques for Photovoltaic Applications under supervision of Dr Shashi Paul at Emerging Technologies Research Centre (EMTERC), De Montfort University. 

Previously having worked in Bharat Electronics Limited (BEL) and ACT Television in Bangalore, India, he also has experience working with network and communication Systems. Moreover, he has also worked as research assistant and as a lecturer (part-time) at DMU. His teaching skills reflects the extensive involvement in innovative research in Silicon Nanowire research for development of Solar Cells and Li-ion Batteries.

Growth of Silicon Nanowires for electronic devices such as solar cells, two terminal memory and Li-Ion batteries are his forte. Apart from inorganic solar cells, he also worked on the organic counterpart. Other researches include investigation of thin films transparent conductors, study on nickel oxide thin films, use of dielectric nanoparticles to enhance efficiency of solar cells, perovskite materials, metal-organic compounds and thin film electronics. Most of these researches include the patented Ra nanowire growth process that was claimed by Dr Shashi Paul from EMTERC in De Montfort University.

He is a photographer enthusiast and likes spending spare time with friends and family.
