Nyquist relation and its validity for piezoelectric ceramics considering temperature

In this paper, we focused on validity of the Nyquist relation for piezoelectric ceramics in temperatures 303 K - 393 K. The electrical impedance and noise spectral density were measured and compared for every 10 K in freque...

Relation between the internal stress measured in creep and the stress generated by the dislocation structure in the fcc metals

and temperature was derived from steady-state creep rate data. The result determined the expected character of the applied stress- and temperature dependence of the dislocation density which was considered the microstructu...

Relation of defects and grain boundaries to transport and photo-transport: solved and unsolved problems in microcrystalline silicon

Defects and grain boundaries play a crucial role in the dark and photo-transport of charge carriers. Surprisingly, the transport (trapping and recombination) in microcrystalline silicon is better understood at low temperatures, while room-
