How does the preparation strategy influence the gold cap of thermophoretic Janus swimmers and their propulsion?
Franziska Braun, Michael Florian Peter Wagner, Maria Eugenia Toimil-Molares +1
The motion of partly gold (Au)-coated Janus particles under laser irradiation is caused by self-thermophoresis. Despite numerous studies addressing this topic, the impact of the pr…
Highly Rectifying Conical Nanopores in Amorphous SiO2 Membranes for Nanofluidic Osmotic Power Generation and Electroosmotic Pumps
Alexander Kiy, Shankar Dutt, Christian Notthoff +3
Nanopore membranes are a versatile platform for a wide range of applications ranging from medical sensing to filtration and clean energy generation. To attain high-flux rectifying…
Analysis of nanometre sized aligned conical pores using SAXS
A. Hadley, C. Notthoff, P. Mota-Santiago +6
Small angle X-ray scattering (SAXS) was used to quantitatively study the morphology of aligned, mono-disperse conical etched ion tracks in thin films of amorphous silicon dioxide w…
Enhancing laser-driven proton acceleration by using micro-pillar arrays at high drive energy
Dimitri Khaghani, Mathieu Lobet, Björn Borm +8
The interaction of micro- and nano-structured target surfaces with high-power laser pulses is being widely investigated for its unprecedented absorption efficiency. We have develop…
Intra-wire coupling in segmented Ni/Cu nanowires deposited by electrodeposition
Philip Sergelius, Ji Lee, Olivier Fruchart +18
Segmented magnetic nanowires are a promising route for the development of three dimensional data storage techniques. Such devices require a control of the coercive field and the co…
Spatio-Temporal Imaging of the Acoustic Field Emitted by a Single Copper Nanowire Copper Nanowires Fabrication
Cyril Jean, Laurent Belliard, Thomas W. Cornelius +5
The monochromatic and geometrically anisotropic acoustic field generated by 400 nm and 120 nm diameter copper nanowires simply dropped on a 10 m silicon membrane is investigated…
Direct Observation of Propagating Gigahertz Coherent Guided Acoustic Phonons in Free Standing Single Copper Nanowires
Cyril Jean, Laurent Belliard, Thomas W. Cornelius +5
We report on gigahertz acoustic phonon waveguiding in free-standing single copper nanowires studied by femtosecond transient reflectivity measurements. The results are discussed on…
Cu codoping control over magnetic precipitate formation in ZnCoO nanowires
S. Granville, E. Matei, I. Enculescu +1
Using electrodeposition, we have grown nanowires of ZnCoO with Cu codoping concentrations varying from 4-10 at.%, controlled only by the deposition potential. We demonstrate contro…
Efficient terahertz emission from InAs nanowires
Denis V. Seletskiy, Michael P. Hasselbeck, Jeffrey G. Cederberg +5
We observe intense pulses of far-infrared electromagnetic radiation emitted from arrays of InAs nanowires. The THz radiation power efficiency of these structures is about 15 times…
Observation of Space-Charge-Limited Transport in InAs Nanowires
Aaron M. Katzenmeyer, François Léonard, A. Alec Talin +4
Recent theory and experiment have suggested that space-charge-limited transport should be prevalent in high aspect-ratio semiconducting nanowires. We report on InAs nanowires exhib…
