Title: How to Coat Zigzag CNT with Gold Nanoparticles or silver nano particle?
Post by: techenthusiast on February 20, 2025, 09:41

Dear Experts,

Good afternoon, I have one question regarding how to coat Zigzag CNT with gold or silver nanoparticles.  Also how to make a CNT-based junction or channel to form a Source and drain as a gold electrode with proper channel length maintained?

Just to ask: Is this example (https://docs.quantumatk.com/tutorials/molecular_device/molecular_device.html) aligned with my second question?

Any kind of valuable suggestions would be highly appreciated.

Also, Can we change the metal gate of the spatial region? For example Au metal gate.

Kindly advise further.

You can make any system you want, with nanoparticles etc, by just adding the right atoms in the right places.

You can not choose the material of the spatial regions, but the voltage applied to the gate should be calibrated for the workfunction of the metal, as discussed here:
