I was very much taken with carbon fibers because they seemed like the perfect medium to explore transport studies in carbon-based systems.
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.
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.
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.
