Ultrafast Dynamics of Massive Dirac Fermions in Bilayer Graphene
Søren Ulstrup, Jens Christian Johannsen, Federico Cilento +14
Bilayer graphene is a highly promising material for electronic and optoelectronic applications since it is supporting massive Dirac fermions with a tuneable band gap. However, no c…
Direct view on the ultrafast carrier dynamics in graphene
Jens Christian Johannsen, Søren Ulstrup, Federico Cilento +11
The ultrafast dynamics of excited carriers in graphene is closely linked to the Dirac spectrum and plays a central role for many electronic and optoelectronic applications. Harvest…
Detecting the local transport properties and the dimensionality of transport of epitaxial graphene by a multi-point probe approach
Lucas Barreto, Edward Perkins, Jens Johannsen +5
The electronic transport properties of epitaxial monolayer graphene (MLG) and hydrogen-intercalated quasi free-standing bilayer graphene (QFBLG) on SiC(0001) are investigated by mi…
