THERMOELECTRIC PROPERTIES OF InSb NANOWIRES ABOVE ROOM TEMPERATURE

The thermoelectric properties of bandles of indium antimonide nanowires with a diameter of about 5 nm have been measured in the temperature range 80-400 K. Natural chrysotile asbestos consisting of parallel nanotubes was used for nanowire preparation. The temperature dependences of the thermoelectric power and the electrical conductance of these samples have been measured. It is shown that the electrical conductance of nanowires increases very rapidly with increasing temperature and the thermopower grows almost linearly in the whole temperature range studied. These specific features of th
