Results of electrical characterization of Au nucleated InAs₁ˍₓSbₓnanowiresgrown by molecular beam epitaxy are reported. An almost doubling of the extracted field effect mobility compared to reference InAsnanowires is observed for a Sb content of x = 0.13. Pure InSbnanowires on the other hand show considerably lower, and strongly diameter dependent, mobility values. Finally, InAs of wurtzite crystal phase overgrown with an InAs₁ˍₓSbₓ shell is found to have a substantial positive shift in...[Show more]
