Abstract:

We measure electrical transport on networks of single-wall nanotube ropes as a function of temperature T, voltage V, and pressure up to 22 GPa. We observe Luttinger liquid (LL) behavior, a conductance Tα, and a dynamic conductance Vα. With pressure, conductance increases while α decreases, enabling us to test the theoretical prediction for LL behavior on the α dependence of the T and V independent coefficient of the tunneling conductance, and to obtain the high frequency cutoff of LL modes. The possible transition to a Fermi liquid at α→0 is unattainable, as nanotubes collapse to an insulating state at high pressures. © 2005 The American Physical Society.
