Metastable and Nanostructured Materials

Carbon Nanotubes from Pre-Defined Catalyst Particles

Since their discovery by Iijima in 1991, carbon nanotubes (CNTs) have stimulated rapidly expanding research because of potential technological application including their use in electronics or as sensors. An enhanced lateral resolution in magnetic force microscopy when using ferromagnetically filled CNTs as magnetic tips, the construction of nanoscale mechanical actuators, or the realization of nanorelay concepts are examples for the  technological impact of CNTs. The main efforts in our group are on the one hand to study and control the growth of CNTs by using pre-defined catalyst particles. And on the other hand, we make use of the atomic resolution in the aberration-corrected transmission electron microscope at low accelerating voltages in order to investigate the internal interface between the CNT and the catalyst particle.

The following materials systems and topics are currently or have until recently been under investigation:
