Nanoimprint lithography using vertically aligned carbon nanostructures as stamps is reported. The functionality of the stamp is demonstrated through lift-off and etch-back processes after pattern replication. The imprint process is robust and the stamp structures survived more than 50 consecutive imprints. In this paper we demonstrate this for feature sizes(More)
We describe a fast and cost-effective process for the growth of carbon nanofibers (CNFs) at a temperature compatible with complementary metal oxide semiconductor technology, using highly stable polymer-Pd nanohybrid colloidal solutions of palladium catalyst nanoparticles (NPs). Two polymer-Pd nanohybrids, namely poly(lauryl(More)
We report on electrical properties and microstructure of epitaxial thin NbN films grown on 3C-SiC/Si substrates by means of reactive magnetron sputtering. A complete epitaxial growth at the NbN/3C-SiC interface has been confirmed by means of high-resolution transmission electron microscopy (HRTEM) along with x-ray diffractometry (XRD). Resistivity(More)
We present a new design approach for the 90° directional coupler with very low amplitude imbalance. The primary feature of this quadrature coupler is the introduction of a controllable ripple in the operational band for achieving a better overall amplitude balance. This design concept is demonstrated through a 90° branch-line hybrid for the 4 – 7.9 GHz band(More)
Chalmers Publication Library (CPL) offers the possibility of retrieving research publications produced at Chalmers University of Technology. It covers all types of publications: articles, dissertations, licentiate theses, masters theses, conference papers, reports etc. Since 2006 it is the official tool for Chalmers official publication statistics.
