| 中文摘要 | We report electrical conductance and thermopower measurements on InA.s nanowires synthesized by chemical vapor deposition. Gate modulation of the thermopower of individual InA.s nanowires with a diameter around 20 nm is obtained over T = 40-300 K. At low temperatures (T < similar to 100 K), oscillations in the thermopower and power factor concomitant with the stepwise conductance increases are observed as the gate voltage shifts the chemical potential of electrons in InAs nanowire through quasi-one-dimensional (ID) subbands. This work experimentally shows the possibility to modulate semiconductor nanowire's thermoelectric properties through ID subband formation in the diffusive transport regime for electron, a long-sought goal in nanostructured thermoelectrics research. Moreover, we point out the scattering (or disorder) induced energy level broadening as the limiting factor in smearing out the ID confinement enhanced thermoelectric power factor. |
