Pressure control of conducting channels in single-wall carbon nanotube networks

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...
