Autocatalytic MBE growth of GaAs nanowires on oxidized Si(100)
Janusz Sadowski, Piotr Dluzewski, Janusz Kanski
GaAs nanowires were grown by molecular beam epitaxy on Si(100) substrates covered with 5 nm SiO2. The growth was performed with As4 at low, close to stoichiometric, As4/Ga flux rat…

Twinning superlattices in indium phosphide nanowires
Rienk Algra, Marcel Verheijen, Magnus Borgstrom +5
Here, we show that we control the crystal structure of indium phosphide (InP) nanowires by impurity dopants. We have found that zinc decreases the activation barrier for 2D nucleat…

Metal-insulator transition and giant anisotropic magnetoresistance in ultra thin (Ga,Mn)As
R. R. Gareev, A. Petukhov, M. Schlapps +4
MBE-grown, 5 nm-thick annealed Ga0.95Mn0.05As films with Tc~90K demonstrate transition from metallic to insulating state below To~10K, where sheet resistances Rsh~h/e2 and both lon…
