The key figure of merit, the capillary performance parameter (defined as K/R eff ), for both single and polycrystalline. (a) The capillary performance parameter of the individual crystalline grains of 10−3 to 10−2 µm (filled markers) is superior to that of polycrystalline samples ranging 10−5 to 10−3 µm (unfilled markers). (b) The capillary performance parameter of single crystalline grains as a function of porosity ϕ. The dashed lines are predictions from the CFD calculations.
