Three-dimensional Optical Reconstruction of colloidal electrokinetics via multiplane imaging
Flip de Jong, Pablo Diez-Silva, Jui-Kai Chen +16
Sorting, filtering, moving and controlling colloidal particles is crucial in many fields, ranging from chemistry to biology and physics. Dielectrophoresis is an outstanding tool fo…
Tuning the Fano resonance between localized and propagating surface plasmon resonances for refractive index sensing applications
Kristof Lodewijks, Jef Ryken, Willem Van Roy +3
Localized and propagating surface plasmon resonances are known to show very pronounced interactions if they are simultaneously excited in the same nanostructure. Here we study the…
Method for Flow Measurement in Microfluidic Channels Based on Electrical Impedance Spectroscopy
Nima Arjmandi, Chengxun Liu, Willem Van Roy +2
We have developed and characterized two novel micro flow sensors based on measuring the electrical impedance of the interface between the flowing liquid and metallic electrodes emb…
Voltage controlled spin injection in a (Ga,Mn)As/(Al,Ga)As Zener diode
P. Van Dorpe, W. Van Roy, J. De Boeck +5
The spin polarization of the electron current in a p-(Ga,Mn)As-n-(Al,Ga)As-Zener tunnel diode, which is embedded in a light-emitting diode, has been studied theoretically. A series…
Quantitative Study of Magnetotransport through a (Ga,Mn)As Single Ferromagnetic Domain
S. T. B. Goennenwein, S. Russo, A. F. Morpurgo +3
We have performed a systematic investigation of the longitudinal and transverse magnetoresistance of a single ferromagnetic domain in (Ga,Mn)As. We find that, by taking into accoun…
Enhanced annealing effect in an oxygen atmosphere on GaMnAs
M. Malfait, J. Vanacken, W. Van Roy +2
We report on in-situ resistivity measurements on GaMnAs during post-growth annealing in different atmospheres. A drop in the resistivity is observed when the GaMnAs is exposed to o…
