Spectroscopic comprehension of Mott-Hubbard insulator to negative charge transfer metal transition in LaNi_{x}V_{1-x}O_{3} thin films
Anupam Jana, Sophia Sahoo, Sourav Chowdhury +4
The room temperature (300 K) electronic structure of pulsed laser deposited LaNi_{x}V_{1-x}O_{3} thin films have been demonstrated. The substitution of early-transition metal (TM)…
Effective separation of photogenerated electron-hole pairs by radial field facilitates ultrahigh photoresponse in single semiconductor nanowire photodetectors
Shaili Sett, Arup Kumar Raychaudhuri
We report an investigation on the observation of ultrahigh photoresponse (photogain, G_Pc>106) in single nanowire photodetectors of diameter < 100 nm. The investigation which is a…
Broad Band Single Germanium Nanowire Photodetectors with Surface Oxide Controlled High Optical Gain
Shaili Sett, Ankita Ghatak, Deepak Sharma +2
We have investigated photoconductive properties of single Germanium Nanowires(NWs)of diameter less than 100 nm in the spectral range of 300 to 1100 nm showing ultra large peak Resp…
Enhanced broad band photoresponse of a partially suspended horizontal array of Silicon microlines fabricated on Silicon-On-Insulator wafers
Shaili Sett, Vishal Kumar Aggarwal, Achintya Singha +2
We report a high Responsivity broad band photo-detector working in the wavelength range 400 nm to 1100 nm in a horizontal array of Si microlines (line width ~1 micron) fabricated o…
Observation of decoupling of electrons from phonon bath close to a correlation driven metal-insulator transition
Sudipta Chatterjee, Ravindra Singh Bisht, V. R. Reddy +1
We observed that close to a Mott transition, over a small temperature range, the predominance of slow relaxations leads to decoupling of electrons from the thermal bath. This has b…
Temperature-dependent thermal conductivity of a single Germanium nanowire measured by Optothermal Raman Spectroscopy
S. Sett, V. K. Aggarwal, A. Singha +1
We investigate temperature dependent thermal conductivity k(T) in a single Ge nanowire (NW) using Optothermal Raman Spectroscopy which utilizes the temperature dependence of Raman…
