  • Publication number: 20100127242
    Abstract: Methods and devices for transparent electronics are disclosed. According to an embodiment, transparent electronics are provided based on transfer printed carbon nanotubes that can be disposed on both rigid and flexible substrates. Methods are provided to enable highly aligned single-walled carbon nanotubes (SWNTs) to be used in transparent electronics for achieving high carrier mobility while using low-temperature processing. According to one method, highly aligned nanotubes can be grown on a first substrate. Then, the aligned nanotubes can be transferred to a rigid or flexible substrate having pre-patterned gate electrodes. Source and drain electrodes can be formed on the transferred nanotubes. The subject devices can be integrated to provide logic gates and analog circuitry for a variety of applications.
