  • Electron transport properties of carbon nanotubes 
    Seshadri, Ram; Aiyer, Hemanthkumar N; Govindaraj, A; Rao, C N R (Pergamon-Elsevier Science Ltd, 1994-07)
    Electrical resistivity measurements of bulk samples of carbon nanotubes show that the resistivity behaviour of nanotubes is comparable to that of graphite. Thermopower behaviour of nanotubes is similar to that of certain ...
  • Investigations of carbon nanotubes 
    Seshadri, Ram; Govindaraj, A; Aiyer, Hemanthkumar N; Sen, Rahul; Subbanna, G N; Raju, A R; Rao, C N R (Current Science Association, 1994-06-10)
    Experiments have been carried out to optimize the yields of carbon nanotubes obtained by the arc-evaporation of graphite. Other types of carbon particles such as nanocrystalline graphite usually present along with the ...
  • Investigations of Pd clusters by the combined use of HREM, STM, high-energy spectroscopies and tunneling conductance measurements 
    Aiyer, Hemanthkumar N; Vijayakrishnan, V; Subbanna, G N; Rao, C N R (Elsevier Science BV, 1994)
    Palladium clusters deposited on carbon substrates by vacuum evaporation have been examined by high resolution electron microscopy and scanning tunneling microscopy to obtain the size distributions of the clusters. Pd(3d) ...
  • Scanning tunneling microscopy and spectroscopy of C70 thin films 
    Aiyer, Hemanthkumar N; Govindaraj, A; Rao, C N R (Indian Academy Of Sciences, 1994-11)
    Scanning tunneling microscopy of C-70 films deposited on HOPG and gold substrates has been carried but to investigate the 2D packing, defects and disorder. Besides providing direct evidence for orientational disorder, high ...
