Nano-molar to milli-molar level Ag (I) determination using absorption of light by ZnS QDs without organic ligand
Rabindra Nath Juine, S. Amirthapandian, S. Dhara +1
Despite of useful applications of Ag, it is hazardous to health and environment and hence early detection is required. Crystal defects influencing optical property is less likely u…
In-situ formation of SiGe alloy by electron beam evaporation and the effect of post deposition annealing on the energy band gap
Twisha Tah, Ch. Kishan Singh, S. Amirthapandian +5
We report the synthesis of polycrystalline (poly)-SiGe alloy thin films through solid state reaction of Si/Ge multilayer thin films on Si and glass substrates at low temperature of…
Localized Charge Transfer Process and Surface Band Bending in Methane Sensing by GaN Nanowires
A. Patsha, P. Sahoo, S. Amirthapandian +5
The physicochemical processes at the surfaces of semiconductor nanostructures involved in electrochemical and sensing devices are strongly influenced by the presence of intrinsic o…
Study of ion beam induced mixing in nano-layered Si/C multilayer structures
Ram Prakash, S. Amirthapandian, D. M. Phase +3
The effects of ion beam induced atomic mixing and subsequent thermal treatment in Si/C multilayer structures are investigated by use of the technique of grazing incidence X-ray dif…
