“…All the sample surfaces, each of which had an area of 2.5 mm Â 2 .5 mm, were sputtered using argon ion for 4 min to remove any possible adsorbed substances on surface before measurement, since the EWF is very sensitive to surface contamination. [17][18][19][20] The measurement was conducted immediately after sputtering. The instrument was operated in ultra high vacuum of 3 Â 10 À8 Torr.…”

Mechanical and thermal behaviors of nitrogen-doped Zr-Cu-Al-Ag-Ta--An alternative class of thin film metallic glass Appl.In this article, we demonstrate that the electron work function (EWF) as an intrinsic parameter can provide information or clues in a simple or straightforward way for material design, modification, and development. A higher work function of a material represents a more stable electronic state, which consequently generates a higher resistance to any attempt of changing the electronic state and other corresponding states, e.g., changes in structure or microstructure caused by mechanical and electrochemical actions. Using Cu-Ni alloy as an example, we demonstrate the correlation between the EWF and Young's modulus of the material as well as its hardness. The properties of a material can be modified using elements with appropriate work functions. This is also applicable for tailoring inter-phase boundaries or interfaces. V C 2013 AIP Publishing LLC.
