Epitaxial films of La1−xMnO3 exhibiting CMR prepared using nebulized spray pyrolysis

Raju, A R; Aiyer, Hemantkumar N; Nagaraju, B Venkata; Mahendiren, R; Raychaudhuri, A K; Rao, C N R (IOP Publishing Ltd, 1997-11-21)

Nebulized spray pyrolysis has been employed to deposit thin films of cation-deficient LaMnO3 on LaAlO3(100) substrates. The epitaxial nature of these films has been established by x-ray diffraction as well as high-resolution ...
Epitaxial Nature of the Films of LaNiO3, Pb(Zr0.5Ti0.5)O3, and La0.95Mn0.95O3 Obtained by Nebulized Spray Pyrolysis

Aiyer, Hemantkumar N; Raju, A R; Subbanna, G N; Rao, C N R (American Chemical Society, 1997-03)

Films of complex oxide materials deposited on single-crystal substrates by means of nebulized spray pyrolysis have been investigated for their epitaxial nature by employing X-ray rocking curve studies and high-resolution ...
Erratum - Orientational disorder and other aspects of C70 and C60 - C70 films deposited on single-crystal substrates

Aiyer, Hemantkumar N; Govindaraj, A; Rao, C N R (Taylor & Francis Ltd, 1996-03)
Fullerenes and other carbon forms: studies by STM and cognate techniques

Rao, C N R; Aiyer, Hemantkumar N; Seshadri, Ram; Govindaraj, A (Elsevier Science SA Lausanne, 1996-02)

Solid-state properties of fullerenes C-60 and C-70 With particular reference to orientational ordering, structural features and photopolymerization of the films, ferromagnetism in C-60-TDAE and interaction of fullerene ...
An Investigation of Well-Characterized Small Gold Clusters by Photoelectron Spectroscopy, Tunneling Spectroscopy, and Cognate Techniques

Rao, C N R; Vijayakrishnan, V; Aiyer, Hemantkumar N; Kulkarni, G U; Subbanna, G N (American Chemical Society, 1993-10-28)

After microscopic characterization of the size distributions of gold clusters, deposited on carbon substrates by vacuum evaporation or by soft landing, Au(4f) binding energy of the clusters has been measured as a function ...
Orientational disorder and other aspects of C70 and C60-C70 films deposited on single-crystal substrates

Aiyer, Hemantkumar N; Govindaraj, A; Rao, C N R (Taylor & Francis Ltd London, 1995-09)

C-70 films deposited on highly oriented pyrolytic graphite (HOPG), Ag(110), Ag(111) and Pt(110) substrates have been investigated by scanning tunnelling microscopy. Interesting observations on novel molecular arrangements, ...
Oriented Films of LaNiO3 and Other Members of the Lan+1NinO3n+1 Series, LaCuO3-δ and Pb(Z r0.52Ti0.48)O3, Obtained by Nebulized Spray Pyrolysis

Raju, A R; Aiyer, Hemantkumar N; Rao, C N R (American Chemical Society, 1995)

The technique of nebulized spray pyrolysis has been explored to find out whether oriented films of certain important oxides can be produced on single-crystal substrates by this relatively gentle method. Starting with ...
Polymerization and Pressure-Induced Amorphization of C60 and C70

Rao, C N R; Govindaraj, A; Aiyer, Hemantkumar N; Seshadri, Ram (American Chemical Society, 1995-11-16)

Scanning tunneling microscopy of solid films of C-60 and C-70 clearly demonstrate the occurrence of photochemical polymerization of these fullerenes in the solid state. X-ray diffraction studies show that such a polymerization ...
A study of copper films obtained from the nebulized spray pyrolysis of different precursors

Aiyer, Hemantkumar N; Parashar, Sachin; Raju, A R; Shivashankar, S A; Rao, C N R (IOP Publishing Ltd, 1999-01-07)

Metallic copper films have been deposited on Si(100) substrates by nebulized spray pyrolysis of Cu(acac)(2), Cu(hfac)(2) and Cu(dpm)(2). The structure and morphology of the films have been examined by x-ray diffraction and ...
Tunneling studies on single crystals of superconducting Bi2Ca1−xYxSr2Cu2O8+δ

Srikanth, H; Raychaudhuri, A K; Rao, C R Venkateswara; Ramasamy, P; Aiyer, Hemantkumar N; Rao, C N R (Elsevier Science BV, 1992-10-01)

Tunneling studies have been carried out on single crystals of Bi2Ca1−xSrxCu2O8+δ over a wide range of compositions wherein the hole concentration varies by a factor of 2.5. The 2Δ value varies between 25 meV and 75 meV ...
