In this work we use atomic force microscopy to investigate the influence of the annealing temperature on the formation of nano-clusters in our growth technique for carbon nanotubes. Cluster formation is carried out just before in situ growth of carbon nanotubes from a methane feedstock by means of catalytic chemical vapor deposition where the clusters act as the catalyst. Since cluster size and distribution...
In this work we use atomic force microscopy to explore carbon nanotubes (CNTs) which are grown by means of catalytic chemical vapor deposition (CCVD). The used process can be utilized to fabricate hundreds of carbon nanotube field-effect transistors (CNTFETs) for logic as well as for power device applications. The application type is selected through specially patterned source/drain contacts which...
In this paper we investigate the feasibility of carbon nanotubes (CNTs) for power applications. On the basis of a process which fabricates thousands of carbon nanotube field-effect transistors (CNTFETs) by means of catalytic chemical vapor deposition (CCVD) we will show that CNTFETs are capable to provide a sufficiently high current to drive a light-emitting diode (LED).
In the future of nanoelectronics, the use of pure silicon based devices will not be possible anymore since the limit of silicon are already reached. Carbon seems to be a great alternative to build high performance electronic devices. Carbon nanotube field-effect transistors can be used as active device in integrated circuits, as memory cell in numerous applications. More recently, graphene-based transistors...
