Structural and optical properties of ZnO nanostructures on nanostructured porous silicon by thermal chemical vapour deposition method / Hartini Ahmad Rafaie

Zinc oxide (ZnO) is a direct wide band gap semiconductor material of 3.3 eV and has a large excitation binding energy of 60 meV. The non-toxicity, thermally stable and the wide availability of its component raw materials give additional advantages for ZnO to be used in many applications. In this the...
