Electric field and potential around localized scatterers in thin metal films studied by scanning tunneling potentiometry
Geetha Ramaswamy, A. K. Raychaudhuri
Direct observation of electric potential and field variation near local scatterers like grain boundaries, triple points and voids in thin platinum films studied by scanning tunneli…
Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with a…
Kinetics of electric field induced oxygen ion migration in epitaxial metallic oxide films
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report the observation of curent induced change of resistance of thin metallic oxide films. The resistance changes at a very low current (current density $J \geq 1…
The Density of States of hole-doped Manganites: A Scanning Tunneling Microscopy/Spectroscopy study
Amlan Biswas, Suja Elizabeth, A. K. Raychaudhuri +1
Variable temperature scanning tunneling microscopy/spectroscopy studies on single crystals and epitaxial thin films of hole-doped manganites, which show colossal magnetoresistance,…
Disorder effects in electronic structure of substituted transition metal compounds
D. D. Sarma, A. Chainani, S. R. Krishnakumar +9
Investigating LaNi(1-x)M(x)O3 (M = Mn and Fe), we identify a characteristic evolution of the spectral function with increasing disorder in presence of strong interaction effects ac…
