  • Bolometric detection of terahertz quantum cascade laser radiation with graphene-plasmonic antenna arrays 
    Degl'Innocenti, Riccardo; Xiao, Long; Kindness, Stephen J.; Kamboj, Varun S.; Wei, Binbin; Braeuninger-Weimer, Philipp; Nakanishi, Kenichi; Aria, Adrianus Indrat; Hofmann, Stephan; Beere, Harvey E.; Ritchie, David A. (IOP Publishing, 2017-03-27)
    We present a fast room temperature terahertz detector based on graphene loaded plasmonic antenna arrays. The antenna elements, which are arranged in series and are shorted by graphene, are contacting source and drain ...
  • Parameter space of atomic layer deposition of ultra-thin oxides on graphene 
    Aria, Adrianus Indrat; Nakanishi, Kenichi; Xiao, Long; Braeuninger-Weimer, Philipp; Sagade, Abhay A.; Alexander-Webber, Jack; Hofmann, Stephan (ACS Applied Materials and Interfaces, 2016-10-10)
    Atomic layer deposition (ALD) of ultrathin aluminum oxide (AlOx) films was systematically studied on supported chemical vapor deposition (CVD) graphene. We show that by extending the precursor residence time, using either ...
