We investigate transport through 5–10 nm thin epitaxial GaAs(001) and (110) barriers sandwiched between polycrystalline iron films. It turns out that tunnelling is the dominant transport mechanism; this is indicated by a nonlinear I–V-characteristic, an exponential dependence of the tunnelling current on the barrier thickness and the temperature dependence of the current. We observe a pronounced ...
