在 1–106Hz 频率范围内，在三种电解质（10−3M 和 ）中测量了单晶的 5 个原始面的阻抗。确定了最快弛豫电容元件，并测量其值作为电极电势的函数。该电容的主要贡献在于双层电容。测量五个晶面的零电荷电势。零电荷电势随晶面的变化很小。 “平均”值是相对于 SCE 的。零电荷的电势与报道的 和 Ru 金属的功函数密切相关。
The impedance of 5 virgin faces of single crystal was measured over the frequency range of 1–106Hz, in three electrolytes—10−3M and and . The fastest relaxing capacitive element was identified, and its values measured as a function of the electrode potential. A major contribution to this capacitance is due to the double layer capacitance. The potential of zero charge in was measured for the five crystalline faces. The variations of the potential of zero charge with the crystalline faces are small. "Average" value is vs. SCE. The potential of zero charge correlates well with the reported work functions of and Ru metal.
