   Sammanfattning : The synthesis of vertically aligned carbon nanofibers (VACNFs) by direct current plasma enhanced chemical vapor deposition (dc PECVD) has presented a unique opportunity to realize nanoscale three-dimensional devices at a reasonable cost. The determinism offered by the synthesis process in terms of control over the spatial and the geometrical properties of the resulting nanofibers provides a powerful tool to implement a wide range of applications from nanoelectromechanical systems to biological devices.
