• Depth resolved luminescence from oriented ZnO nanowires 

      Rosenberg, R. A.; Haija, M. Abu; Vijayalakshmi, K.; Zhou, Jun; Xu, Sheng; Wang, Z. L. (Zhong Lin) (Georgia Institute of TechnologyAmerican Institute of Physics, 2009-12-14)
      We have utilized the limited penetration depth of x-rays to study the near-surface properties of vertically aligned ZnO nanowires. For an energy of 600 eV the penetration depth varies between 3 and 132 nm as the incidence ...
