摘要
The chemisorption energy of hydrogen on semiconductor/alloy composite substrates are investigated. (?)g the conplex-energy-plane integration approach. The electronic properties of the substrate are described by using the Green function method within the framework of the tight-binding approximation. The coherent potential approximation (CPA) is used to deal with the alloys. specific calculations are performed for the H-ZnO/Ni_xCu_(1-x) and H-ZnO/Ag_xpd_(1-x) systems.
