Mo/Si multilayer mirrors are used for extreme ultraviolet (EUV) lithography. The formation of hydrogen-induced blisters in the is a problem that reduces reflectance mirror. To evaluate blister-resistance EUV mirrors, blister processes multilayers with capping layer were investigated using high-frequency hydrogen plasma system as ion source under varying exposure conditions. As result, it was ob...

Physicochemical properties, ionicity, and fragility for protic ionic liquids (PILs) based on the protonation of the extremely fragile molecular liquid decahydroisoquinoline (DHiQ) by various Brønsted acids have been studied. The ionicity was evaluated using the Walden plot diagnostic, while the m-fragility (slope of T(g)-scaled Arrhenius plot at T(g)) was quantitatively measured by the Moynihan...

On short time scales an underlying Arrhenius temperature dependence of the diffusion constant can be extracted from the fragile, super-Arrhenius diffusion of a binary Lennard-Jones mixture. This Arrhenius diffusion is related to the true super-Arrhenius behavior by a factor that depends on the average angle between steps in successive time windows. The correction factor accounts for the fact th...

We discuss possible extraneous effects entering in the conventional measures of “fragility” at atmospheric pressure that may obscure a characterization genuine super-Arrhenius slowdown relaxation. first consider role density, which increases with decreasing temperature constant pressure, and then potential influence high-temperature dynamical behavior associated activation energy scale. These t...

A non-Arrhenius model based on the Mittag-Leffler function has been conceived as a basic concept. This approach allows modelling both sub-Arrhenius and super-Arrhenius behaviours giving rise to modified temperature integrals.

Perovskite-type metal oxides such as Y-doped BaMO3 (M = Zr/Ce) have drawn considerable attention proton-conducting electrolytes for intermediate temperature ceramic electrochemical cells. Improving the proton conductivity at lower temperatures requires a comprehensive understanding of conduction mechanism. By applying high pressure or varying Ce content BaMO3, it is demonstrated that follows Me...
