Special Issue Information
Dear Colleagues,
Since the seminal discovery of carbon nanotubes by Sumio Iijima more than 30 years ago, research interest in this field has grown dramatically due to their unique optical and electronic properties. Synthesized raw tube material usually contains both semiconducting and metallic tubes with a wide diameter and chirality distribution, besides some other impurities, which means that it is usually not good enough for practical usage. Synthetic techniques have been improved substantially by finetuning the catalyst and preparation conditions used. Post-synthesis separation has also been sought out. The purity requirement is heavily dependent on the application. For example, for thin film transistors with channel lengths over 10 um, 99.9% semiconducting purity could be enough, but 99.9999% is desired for high-performance short-channel field-effect transistors. For optical applications, high-purity single-chirality samples are needed. Currently, high semiconducting purity and some single-chirality carbon nanotubes could be easily obtained from solution processes.
The present Special Issue of Nanomaterials is aimed at presenting the current state-of-the-art research related to carbon nanotubes, covering not only the preparation and enrichment process to address purity and chiral selectivity issues but also device applications, such as thin film transistors, photodetectors, single photo emission and sensors. For this Special Issue, we welcome contributions from leading groups in the field and hope to give a balanced view of the current state of the art in this discipline.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nanomaterials is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
