Doping of CNT networks


Stanford Reference:

09-308


Abstract


Researchers in Prof. Zhenan Bao's laboratory have developed a novel, stable and efficient dopant that can substantially increase the conductivity of micro and nano structures. This dopant can be synthesized inexpensively in large quantities, and is easily deposited from the vapor phase or from solution. The dopant can be used for carbon and inorganic technologies including electronic devices (such as transistors, displays, touch screens, sensors, e-paper, and solar cells), thermal conductors, and composite materials.

Stage of Research
The inventors have used this technology to dope carbon nanotubes (CNTs) and carbon fibers, graphene, and a variety of inorganic nano/microstructures.

Ongoing Research
The inventors continue to optimize this dopant to increase conductivity and understand the nature of various dopant molecules on different materials.



Applications


  • Micro/nanostructures for electronics:
    • solar cells
    • flat panel displays
    • e-readers
    • touch screens
    • OLEDs
  • Next generation flexible electronics

Advantages


  • High performance - conductivity increased relative to un-hybridized or doped CNT networks
  • Inexpensive process to produce large quantities of dopant
  • Easy deposition - from vapor phase or solution
  • Stable:
    • indefinitely in ambient temperature
    • past 250o
  • Controlled growth on nano/microstructure
