Nanoscale origins of super-capacitance phenomena
(2019-02-28)
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
Rietveld analysis of CaCu3Ti4O12 thin films obtained by RF-sputtering
(2016-03-01)
Calcium copper titanate, CaCu3Ti4O12, CCTO, thin films with polycrystalline nature have been deposited by RF sputtering on Pt/Ti/SiO2/Si (100) substrates at a room temperature followed by annealing at 600 °C for 2 h in a ...
