Journal ArticleDOI
Crystal structure and physical properties of half-doped manganite nanocrystals of less than 100-nm size
TL;DR: In this article, the structural and property measurements of nanocrystals of half-doped La 05 Ca 05 MnO 3 (LCMO) synthesized by chemical route, having particle size down to an average diameter of 15 nm, were reported.
Journal ArticleDOI
Photoreactivity of ZnO nanoparticles in visible light: Effect of surface states on electron transfer reaction
Sunandan Baruah,Sudarson Sekhar Sinha,Barnali Ghosh,Samir Kumar Pal,A. K. Raychaudhuri,Joydeep Dutta +5 more
TL;DR: In this paper, the authors observed a redshift in the optical absorption shifting from the ultraviolet region to the visible region (400-700 nm) due to the creation of intermediate defect states that inhibit the electron hole recombination process.
Journal ArticleDOI
High sensitivity NH 3 gas sensor with electrical readout made on paper with perovskite halide as sensor material
TL;DR: A cheap, paper electronics based solid state gas sensor to detect NH3 gas selectively with a detection capability of better than 1 ppm with established perovskite halide as a newsolid state gas sensing material that can reach sub ppm sensitivity using simple paper electronics.
Journal ArticleDOI
Variation of Tc and transport properties with carrier concentration in Y- and Pb-doped Bi-based superconductors.
TL;DR: Analysis of the electrical resistivity in the insulating region suggests that the transport is governed by a variable-range-hopping mechanism in the low-temperature region and phonon-assisted hopping of polarons in the high-tem temperature region.
Journal ArticleDOI
Volume collapse in LaMnO 3 caused by an orbital order-disorder transition
TL;DR: In this article, the authors investigated the Jahn-Teller transition accompanied by the orbital order-disorder transition in a high temperature x-ray powder diffraction with synchrotron radiation and also neutron powder diffusion.
