Single-walled carbon nanotubes have a diameter of about 1nm and the length is nearly million times longer. Sigma Aldrich offer SWNT materials and their synthesis with controlled structures is described.
Aldrich Materials Science, in partnership with TDA Research, is pleased to introduce purified Small-Gap Fullerenes (SGFs). The small band gap properties of these fullerenes are excellent for use in photovoltaic devices, as well as antioxidants, semiconductors, sorbents and catalyst supports.
[60]PCBM is present as a single isomer. An interesting feature of [60]PCBM which may correlate with its performance is that it preserves to a high degree the electronic and physical properties of C60. It is used in photovoltaics, fiel effect transistors and photodetectors.
Carbon nanotubes (CNTs) are a form of elemental carbon that resemble graphite in that they consist of a network of carbon atoms arranged in six member rings. Advantages of CoMoCAT multi-walled carbon nanotubes compared to conventional MWNTs are presented.
Single-walled carbon nanotubes (SWNTs) are a mixture of tubes of different chiralities, some of which are electrically conducting and some are semiconducting. It is desirable, for many applications, to isolate the types of nanotubes from one another, such as metallic from semiconducting.
Carbon Nanotube (CNT) Arrays are synthesized by chemical vapour deposition(CVD) systems. This article describes what they are and how to prepare them using VR or vacuum release trays.
The existing tools available to perform infrared spectroscopy and microscopy at the nanometer scale are limited considering all the different near-field microscopes.
Despite graphenes impressive list of promising prospects, it does not have a band-gap, once it is conducting it cannot be switched-off.
