Tuning the workfunction of ZnO through surface doping with Mn from first-principles simulations
Andreas Douloumis, Nikolaos R. E. Vrithias, Nikos Katsarakis +2
Surface doping of ZnO allows for tailoring the surface chemistry of the material while preserving the superb electronic structure of the bulk. Apart from obvious changes in adsorpt…
Electric coupling to the magnetic resonance of split ring resonators
N. Katsarakis, T. Koschny, M. Kafesaki +2
We study both theoretically and experimentally the transmission properties of a lattice of split ring resonators (SRRs) for different electromagnetic (EM) field polarizations and p…
Magnetoresistance and percolation in the LaNi(1-x)Co(x)O3 solid solution
J. Androulakis, Z. Viskadourakis, N. Katsarakis +1
A detailed study of the zero-field electrical resistivity and magnetoresistance for the metallic members of the LaNi_{1-x}Co{x}O3 solid solution with 0.3<=x<=0.6 is reported. The l…
A comparative study of the magnetic and magnetotransport properties between a metallic (x=0.6) and a semiconducting (x=0.2) member of the solid solution LaNixCo1-xO3
J. Androulakis, N. Katsarakis, Z. Viskadourakis +1
We present a comparative study of both the magnetic and magnetotransport properties for two members of the perovskite solid solution LaNixCo1-xO3 (x=0.2, 0.6) located on opposite s…
Realization of La2MnVO6: Search for half-metallic antiferromagnetism?
J. Androulakis, N. Katsarakis, J. Giapintzakis
Single-phase polycrystalline La2MnVO6 samples were synthesized by arc melting and characterized by X-ray diffraction, magnetization and resistivity measurements. We find that the c…
