Цел на проекта

Carbon annotates (CNT) represent the one-dimensional form of carbon. Related to their appealing needle-like structure, they possess a number of peculiar mechanical and electronic properties, which makes them promising candidates for devices-devices. The single walled version of Cants (SWCNT) are even more interesting due to their well defined geometry and small diameter. Doping and modifications of SWCNTs have attracted considerable interest. The C60 doped SWCNT, (C60@SWCNT) combines two fundamental forms carbon. Recently, it has been shown that a suitable high temperature treatment transforms the filled-in C60 into a SWCNT that occupies the interior of a SWCNT. The inner tubes of this double wall carbon annotate (DWCNT) structure are unique as they are formed in a catalyst free environment and such tubes have a highly perfect, defect-less structure as the host institute has demonstrated. Superior mechanical and electronic properties make Decants a promising candidate for applications such as transistor electrodes in future electronics, cantilever material for scanning probe microscopy and many more. DWCNT growth will be studied from C60@SWCNT in successive heat treatment steps using transmission electron microscopy and Raman spectroscopy. We also intend to grow hetero-inner tube Decants starting from heteromolecule@SWCNT. The charge transfer from alkali do pants to DWCNT will be studied using in-site Raman and dc transport studies. It is yet unknown how charge transfer affects the electronic properties of Decants. Individual Decants will be studied using Raman microscopy and scanning probe microscopy. Decants will be isolated on a substrate in low density. Studies of the same individual DWCNT using the these methods enables to correlate the Raman information on the tube diameter and its electronic state with the information attainable from scanning probe microscopy such as annotate felicity (using STM) and joint density of states of Decants (using STS).
