Determination of the band alignment of multi-walled carbon nanotubes decorated with cadmium sulfide

- MWCNTs and CdS composite were grown by the solvothermal method.
- Photoelectron spectroscopy was used to analyze energy levels at the interface.
- The interface shows zero value for the Schottky barrier between MWCNTs and CdS.
- MWCNTs act as ohmic contacts for CdS nanoparticles.
- MWCNTs may act as charge collector in CdS-based devices.
