Abstract

The composition analysis of single Si and Ge nanowires with atom probe tomography is presented. Si and Ge nanowires were grown using Au seeds by the vapor-liquid solid growth process and analyzedusing pulsed-laser atom probe tomography. Statistical analysis of mass spectra with low background counts places an upper bound on Au incorporation of ∼10 ppm. Considering complementary measurements of minority carrier diffusion lengths, it is determined that the use of a Au seed does not significantly influence minority carrier lifetimes in nanowires with a native oxide.
