Journal ArticleDOI
Understanding the 3D structure of GaAs nanowires
Lisa Karlsson,Kimberly A. Dick,Jakob Birkedal Wagner,Jan-Olle Malm,Knut Deppert,Lars Samuelson,L. Reine Wallenberg +6 more
TL;DR: In this paper, the effects of lamellar twinning in epitaxial particle-assisted GaAs B nanowires are investigated in an extensive high resolution electron microscopy (HRTEM) study of the low index zones.
Journal ArticleDOI
Increasing amperometric biosensor sensitivity by length fractionated single-walled carbon nanotubes.
TL;DR: Depending on the average length of the SWCNTs the sensitivity of the amperometric biosensor model system towards oxidation of 1,4-dihydronicotinamide adenine dinucleotide (NADH) was increased by a factor of five and the biosensor exhibited excellent electrocatalytic properties.
Journal ArticleDOI
Radiative recombination in heavily doped p-type germanium
Jakob Birkedal Wagner,Luis Viña +1 more
TL;DR: In this paper, low-temperature photoluminescence studies on heavily doped $p$-type germanium are reported, where direct recombination of nonthermalized minority carriers located at the conduction-band minimum at point $\ensuremath{\Gamma}$ is observed.
Journal ArticleDOI
Radial Nanowire Light-Emitting Diodes in the (AlxGa1-x)yIn1-yP Material System.
Alexander Berg,Sadegh Yazdi,Ali Nowzari,Kristian Storm,Vishal Jain,Neimantas Vainorius,Lars Samuelson,Jakob Birkedal Wagner,Magnus T. Borgström +8 more
TL;DR: The presented results can be a valuable track toward radial nanowire light-emitting diodes in the AlGaInP material system in the red/orange/yellow color spectrum.
Journal ArticleDOI
Nanometer-scale lithography on microscopically clean graphene
W. F. van Dorp,Xiaoyan Zhang,Ben L. Feringa,Jakob Birkedal Wagner,Thomas Willum Hansen,J.Th.M. De Hosson +5 more
TL;DR: A method to remove the amorphous material in order to obtain large areas of microscopically clean graphene flakes is presented and observed that preferential adsorption of the precursor molecules on step edges and adsorbates plays a key role in the deposition on cleaned few-layer graphene.
