Modulation of Carbon Nanotube Metal Contacts in Gaseous Hydrogen Environment
Figure 3
Band diagram of PdNi in contact with CNTs. (a) The band structure as formed in an air ambient. (b) Band structure after PdNi workfunction modification by Hydrogen exposure. On Hydrogen exposure, the PdNi Fermi level () decreases and changes the overlap between metal occupied states and CNT valence band edge (), thereby modulating the metal-CNT contact.
