Electrons are the carriers for electricity, but they are also carriers for thermal energy. This means thermal conductivity is increased when the carrier density is increased.
I would say the first three or four papers on nano-thermoelectricity in bismuth went almost unnoticed, but all of a sudden when Dirac cones came along - pop! - there was huge interest in bismuth-related materials.
Superconductivity helped broaden my professional phase space. When I started my work, it was already known that magnetic fields could quench superconductivity. I found that the transition was not continuous, that superconductivity was initially enhanced in the presence of magnetic fields, then it would suddenly fall off.
A carbon nanotube is just a graphene sheet that's rolled up seamlessly, and this happens in nature; carbon nanotubes are found in mineral deposits around the planet.
My older brother was a musical prodigy, and he got a scholarship to the Bronx House Music School. We moved to the Bronx when I was 4 to be close to his music school. Then I got a music scholarship myself, at the age of 6, but that was for a school down in Greenwich Village. I had to take the elevated train and then the subway to get there.
I was very much taken with carbon fibers because they seemed like the perfect medium to explore transport studies in carbon-based systems.
