Zusammenfassung
We investigate electronic transport properties of Schottky-barrier field-effect transistors (FETs) based on double-walled carbon nanotubes (DWCNTs) with a semiconducting outer shell and a metallic inner one. This kind of DWCNT-FETs shows asymmetries of the I-V characteristics and threshold voltages due to the electron-hole asymmetry of the Schottky barrier. The presence of the metallic inner ...
