XPS evidence for molecular charge-transfer doping of graphene
D. Choudhury, B. Das, D. D. Sarma +1
By employing x-ray photoelectron spectroscopy (XPS), we have been able to establish the occurrence of charge-transfer doping in few-layer graphene covered with electron acceptor (T…
Raman evidence for Orbiton-Mediated Multiphonon Scattering in Multiferroic TbMnO
Pradeep Kumar, Surajit Saha, D. V. S. Muthu +3
Temperature-dependent Raman spectra of TbMnO from 5 K to 300 K in the spectral range of 200 to 1525 cm show five first-order Raman allowed modes and two high frequency m…
NO2 and Humidity Sensing Characteristics of Few-layer Graphene
Anupama Ghosh, Dattatray J. Late, L. S. Panchakarla +2
Sensing characteristics of few-layer graphenes for NO2 and humidity have been investigated with graphene samples prepared by the thermal exfoliation of graphitic oxide (EG), conver…
Semiconductor to metal transition in SWNTs caused by interaction with gold and platinum nanoparticles
Rakesh Voggu, Shrinwantu Paul, Swapan K. Pati +1
Single-walled carbon nanotubes (SWNTs) have been coated with gold and platinum nanoparticles either by microwave treatment or by the click reaction and the Raman spectra of these S…
An electron paramagnetic resonance study of Pr_{0.6}Ca_{0.4}MnO_{3} across the charge ordering transition
Rajeev Gupta, Janhavi P. Joshi, S. V. Bhat +2
We report the first electron paramagnetic resonance studies of single crystals and powders of Pr_{0.6}Ca_{0.4}MnO_{3} in the 300-4.2 K range, covering the charge ordering transitio…
Optical Limiting in Single-walled Carbon Nanotube Suspensions
S. R. Mishra, H. S. Rawat, S. C. Mehendale +5
Optical limiting behaviour of suspensions of single-walled carbon nanotubes in water, ethanol and ethylene glycol is reported. Experiments with 532 nm, 15 nsec duration laser pulse…
