The possibilities for describing sitting postural control using nonlinear methods was investigated during long-term driving. A total of 85 min of motorway driving intervals (n=12) were used for analysis. The results show that contrary to conventional analysis techniques, nonlinear measures were able to identify a threshold behavior describing the change in(More)
In this paper we present results of our recent efforts to understand the mechanical interface behaviour of single-walled carbon nanotubes (CNTs) embedded in metal matrices. We conducted experimental pull-out tests of CNTs embedded in Pd or Au and found maximum forces in the range 10-102 nN. These values are in good agreement with forces obtained from(More)
We report on and emphasize the versatility of conductive atomic force microscopy in characterizing vertically aligned carbon nanotubes (CNTs) aimed to be used in via interconnect technology. The study is conducted on multi-walled CNT arrays vertically grown on a copper-based metal line. Voltage-dependent current mapping and current-voltage characteristics(More)
For Cu/carbon nanotube(CNT) hybrid interconnect technology the growth of CNTs on a conductive substrate connected to Cu lines is required. CNTs were grown by catalytic chemical vapour deposition and the effect of a Cu layer beneath was investigated. By electron energy loss spectroscopy (EELS) we found the Cu to diffuse into the catalyst. This influences CNT(More)
Nanoperforated ZrO<sub>2</sub> membranes, produced via organic/inorganic self-assembly using block copolymer micelles, serve as template for a Co/Pt multilayer stack with out-of-plane magnetic anisotropy. The deposition of the magnetic film results in an array of magnetic nanodots surrounded by a continuous magnetic film. These magnetic dots are found to be(More)
In this work we give an overview about recent developments in the integration technology of CNTs. We focus on wafer level approaches with the CVD and DEP method for growing as well as depositing CNTs in a defined way. So that we present methods to manipulate CNT growth structure, growth mode as well as growth inhibition in thermal CVD processes. This is(More)
In this paper we present our recent efforts to develop an in situ tensile test device for thermo-mechanical characterization of interfaces between single-walled carbon nanotubes (SWCNTs) and metals. For the mechanical tests, the chosen loading condition is a pull-out test. After summarizing results of maximum stresses calculated from molecular dynamics(More)
Experimental results gained by various electrical characterization techniques are discussed and compared for a CNTFET technology, which suffers as almost all emerging technologies from traps in the gate oxide. Based on these results, it is highlighted that, contrary to common practice, a fast data acquisition technique is required to ensure a proper(More)
We present investigations of pull-out tests on CNTs embedded in palladium by means of molecular dynamics (MD) and compare our results of maximum pull-out forces with values of nano scale in situ pull-out tests inside a scanning electron microscope (SEM). Our MD model allows the investigation of crucial influencing parameters on the interface behaviour, like(More)
During the recent years, a significant amount of research has been performed on single-walled carbon nanotubes (SWCNTs) as a channel material in thin-film transistors (Pham et al. IEEE Trans Nanotechnol 11:44-50, 2012). This has prompted the application of advanced characterization techniques based on combined atomic force microscopy (AFM) and Raman(More)
