General description

Produced using CHASM′s patented CoMoCAT synthesis technology, Signis® SG65i is a single-wall carbon nanotube (CNT) product uniquely enriched in semiconducting tubes, with (6,5) chirality being most abundant. Approximately 95% of the CNTs in SG65i are semiconducting, with approximately 41% of those tubes being (6,5) chirality.


Suitable for use in printed semiconductors, photovoltaic devices, sensors, medical research, etc.
