Transport in manganites under high pressure and single-walled carbon nanotubes.
Bradley, Keith.

Transport in manganites under high pressure and single-walled carbon nanotubes. - 135 p.

Chair: Alex K. Zettl.

Thesis (Ph.D.)--University of California, Berkeley, 2001.

This thesis consists of two parts. The first part discusses a high-pressure search for superconductivity in manganites. Colossal magnetoresistance manganites are reviewed. No superconductivity is observed in La0.6Pb 0.4MnO3 or Nd0.66Pb0.33MnO3 at pressures up to 150 kbar and temperatures down to 2.2 K. New techniques for measuring resistance under hydrostatic pressure, developed for this experiment, are described in detail.

520 $a This thesis consists of two parts. The first part discusses a high-pressure search for superconductivity in manganites. Colossal magnetoresistance manganites are reviewed. No superconductivity is observed in La0.6Pb 0.4MnO3 or Nd0.66Pb0.33MnO3 at pressures up to 150 kbar and temperatures down to 2.2 K. New techniques for measuring resistance under hydrostatic pressure, developed for this experiment, are described in detail.
520 $a The second part discusses several transport experiments on single-walled carbon nano-tubes. The thermoelectric power of bulk samples is examined to identify the effect of atmospheric gas. Negative thermopower is discovered in degassed nanotubes. The binding energy of adsorbed oxygen on nanotubes is estimated to be 0.4 eV. A model involving degenerate doping is presented to account for the range of thermopower data. Measurements of 1/<italic>f </italic> noise support the idea that oxygen adds carriers to nanotubes. The last chapter describes an attempt to observe shot noise in carbon nanotube devices. Measurements of noise is measured as a function of frequency between 100 MHz and 1 GHz obviate the 1/<italic>f</italic> noise spectrum. The first measurement is reported, in which diffusive conduction is observed in a nanotube rope device 1 micron long.
