Spin-split bands cause the indirect band gap of (CHNH)PbI: Experimental evidence from circular photogalvanic effect
Daniel Niesner, Martin Hauck, Shreetu Shrestha +7
Long carrier lifetimes and diffusion lengths form the basis for the successful application of the organic-inorganic perovskite (CHNH)PbI in solar cells and lasers. The…
Anomalous Dirac point transport due to extended defects in bilayer graphene
Sam Shallcross, Sangeeta Sharma, Heiko B. Weber
Charge transport at the Dirac point in bilayer graphene exhibits two dramatically different transport states, insulating and metallic, that occur in apparently otherwise indistingu…
Implanted Bottom Gate for Epitaxial Graphene on Silicon Carbide
Daniel Waldmann, Johannes Jobst, Felix Fromm +4
We present a technique to tune the charge density of epitaxial graphene via an electrostatic gate that is buried in the silicon carbide substrate. The result is a device in which g…
The quasi-free-standing nature of graphene on H-saturated SiC(0001)
F. Speck, J. Jobst, F. Fromm +5
We report on an investigation of quasi-free-standing graphene on 6H-SiC(0001) which was prepared by intercalation of hydrogen under the buffer layer. Using infrared absorption spec…
Atmospheric pressure graphitization of SiC(0001)- A route towards wafer-size graphene layers
Konstantin V. Emtsev, Aaron Bostwick, Karsten Horn +11
We have investigated epitaxial graphene films grown on SiC(0001) by annealing in an atmosphere of Ar instead of vacuum. Using AFM and LEEM we observe a significantly improved surfa…
