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…
First principles study of bimetallic NiAg nano-clusters ( 013) : Structural, mixing, electronic and magnetic properties
Soumendu Datta, A. K. Raychaudhuri, Tanusri Saha-Dasgupta
Using spin polarized density functional theory (DFT) based calculations, combined with ab-initio molecular dynamics simulation, we carry out a systematic investigation of the bimet…
Large photoresponse of Cu:TCNQ nanowire arrays formed as aligned nanobridges
Rabaya Basori, K. Das, Prashant Kumar +2
We report for the first time a large photoresponse in an array of charge transfer complex Cu:TCNQ nanowires (average diameter 30 nm) fabricated as a nanobridge device. The device s…
Observation of a Large Photo-response in a Single Nanowire (Diameter ~30 nm) of Charge Transfer Complex Cu:TCNQ
Rabaya Basori, Kaustuv Das, T. Phanindra. Sai +3
We report for the first time large photoresponse in a single NW of the charge transfer complex Cu:TCNQ. We fabricate a metal-semiconductor-metal device with a single NW and focus i…
Non-Gaussian resistance noise in the ferromagnetic insulating state of a hole doped manganite
Sudeshna Samanta, A. K. Raychaudhuri, Ya. M. Mukhovskii
We report the observation of a large 1/f noise in the ferromagnetic insulating state (FMI) of a hole doped manganite single crystal of La0.80Ca0.20MnO3 which manifests hopping cond…
Electrical resistance of Ni nanowires (diameter greater than or equal to 20 nm) near the Curie Temperatures
M. Venkata Kamalakar, A. K. Raychaudhuri
In this letter we report electrical transport measurements on nickel nanowires of diameters down to 20 nm in the region close to its paramagnetic-ferromagnetic transition temperatu…
