• "Magnetoconductance of carbon nanotubes probed in parallel magnetic fields up to 60 T", Jhang, Marganska, del Valle, Skourski, Grifoni, Wosnitza, Strunk, 2011

  Publication

  Magnetoconductance of carbon nanotubes (CNTs) is investigated. We clearly show that a semiconducting CNT can be converted into a metallic one, or vice...
