Sumio Iijima Sumio Iijima (飯島 澄男 "Iijima Sumio", born May 2, 1939) is a Japanese physicist, often cited as the inventor of carbon nanotubes. Although carbon nanotubes had been observed prior to his "invention", Iijima's 1991 paper generated unprecedented interest in the carbon nanostructures and has since fueled intense research in the area of nanotechnology. For this and other work Sumio Iijima was awarded, together with Louis Brus, the inaugural Kavli Prize for nanoscience in 2008.
