Allgemeine Beschreibung

Structure of double walled carbon nanotubes (DWNTs) can be imagined as a two coaxial concentric single walled carbon nanotubes (SWNTs). It has been prepared by catalytic chemical vapor deposition. DWNTs exhibit excellent field emission properties and may be potentially useful as field emission displays (FEDs) and field emission transistors (FETs).

Anwendung

Carbon nanotube, double walled can be used for a variety of applications such as solar cells, nanomechanical resonators, film heaters, biosensors, and field emission displays.

Verpackung

Packaged in glass bottles

Angaben zur Herstellung
