Annual Report (October 2015 to September 2016)

Cochin University SPIE Student chapter celebrated its 11th year of active research related

activities during this year. Since its inception in October 2005, the chapter was really enthusiastic in

various academic activities. At present the chapter have 26 members. The chapter members are currently

working in the areas of Nanophosphors and Quantum wells, Transparent Thin Film Transistors,

Hydrothermal Growth of Nanoparticles, Spintronics, Photovoltaic energy storage materials and devices,

Transparent Conducting Oxides, Ferroelectric Random Access Memories, Holography, Luminescent

materials and Conducting Polymers. All the members are actively participating in the programs organized

by the chapter and Dept. of Physics. This year the following activities were carried out by the SPIE

CUSAT student chapter.

Academic Training

Activities

Physics – Scope and Awareness for School Children April 4-8, 2016 SPIE Student Chapter organized student outreach programs to attract talented students to the fascinating

world of Science and Technology. The six day workshop envisages to provide an opportunity to students

to interact with the faculty members, listen to new developments in scientific fields and also witness some

of the advanced experiments being carried-out in the research laboratories of the Department of Physics

and also to gain hands on experience on various core experiments in Physics, telescope making etc.

Inauguration of the workshop by Dr. J Letha (Hon. Vice Chancellor CUSAT)

Telescope making

National Workshop on “Nanophotonics” ,

18th -19th March, 2016 Department of Physics, Centre for advanced materials and SPIE CUSAT student chapter jointly organized the national workshop on “Nanophotonics”. The workshop was a platform that enabled

young researchers, especially the masters students to share ideas, which inculcated a quest for

knowledge through the spirit of enquiry and research. The two day workshop includes talks by

resource persons from prestigious institutes. A poster presentation by the master students was also

organized.Theme of the Workshop was Hybrid Perovskite Material, 2D-Field Emission Transistors,

2D Materials : Beyond Graphene Quantum Transport in 1D Nanomaterials, Solar Cells and Energy

Storage Materials.
