During the deposition process of high-k gate oxides on Ge, the Ge interface tends to be oxidized to form GeO x , leading to the introduction of interface states which compromise transistor performance. It has been suggested that a Ba termination layer on Ge could fulfill the same passivating role on
The interactions of H and H 2 with W(1 0 0)-c(2 Γ 2)Cu and W(1 0 0) have been investigated through density functional theory (DFT) calculations to elucidate the effect of Cu atoms on the reactivity of the alloy. Cu atoms do not alter the attraction towards top-W sites felt by H 2 molecules approachi
Ge is a promising starting material for device fabrication due to its advantages, which include narrow band gap, high hole mobility, and high solubility for p-type dopants [1,2]. In order to clean the Ge surface prior to gate oxidation, surface oxidation, and etching must occur in succession. Becaus
