通过扫描从电子掺杂到空穴掺杂区域的费米能量，演示了半导体和金属单壁碳纳米管中多子带态密度的热电检测。利用双电层晶体管结构中感应的强电场系统地控制费米能量，从而优化热电功率因数。
Thermoelectric detection of a multisubband density of states in semiconducting and metallic single-walled carbon nanotubes is demonstrated by scanning the Fermi energy from electron-doped to hole-doped regions. The Fermi energy is systematically controlled by utilizing the strong electric field induced in electric-double-layer transistor configurations, resulting in the optimization of the thermoelectric power factor.
