IsoNanotubes are a separated carbon nanotube product developed by NanoIntegris, Inc, a nanotechnology company based in Skokie, Illinois specializing in the production enriched, single-walled carbon nanotubes.[1]
The proprietary technology through which IsoNanotubes are created "spun out of the Hersam Research Group at Northwestern University."[2][3] IsoNanotubes are separated into two types, Semiconducting and Conducting.
Semiconducting
Enriched Semiconducting carbon nanotubes[4]
Conducting
Enriched Conducting carbon nanotubes[5]
Applications
Field-Effect Transistors
Both Wang[6] and Engel[7] have found that NanoIntegris separated nanotubes "hold great potential for thin-film transistors and display applications" compared to standard carbon nanotubes.
Transparent Conductors
Additionally, the ability to distinguish semiconducting from conducting nanotubes was found by Alexander A. Green and Mark C. Hersam to have an effect on conductive films.[8]
Organic Light-Emitting Diodes
Organic Light-Emitting Diodes (OLEDs) can be made on a larger scale and at a lower cost using separated carbon nanotubes.[6]
High Frequency Devices
By using high-purity, semiconducting nanotubes, scientists have been able to achieve "record...operating frequencies above 80 GHz."[9]
