Charge redistribution in electrochemically-actuated mechanical sensors
Many proofs of concept studies have established the mechanical sensitivity of functionalized microcantilevers to a large spectrum of target molecules. However, moving to real-life applications also requires the monitored mechanical effect to be highly specific. Moving towards more specificity in cantilever-based sensing, monitoring the mechanical response of electrochemically actuated microcant...
متن کاملCharge order and superconductivity in low-dimensional organic conductors.
We study the coexistent state of the spin density wave (SDW) and the charge density wave (CDW) in a one-dimensional extended Hubbard model. We find that the coexistent state of SDW and CDW is stabilized in various electron-filling cases when band parameters are for organic conductors. The ground state energies have cusp-like minima at n/4m-fillings, where n and m are integers. The maxima of the...
متن کاملCharge Transport in Polymer Ion Conductors: a Monte Carlo Study
Chain polymers carrying electro-negative atoms (e.g. oxygen or nitrogen) in their repeat unit can act as solvents for certain salts. Well-known examples are Li-salts dissolved in polyethylene-oxide (PEO). At temperatures sufficiently above the glass-transition temperature these polymer-salt solutions show significant DC ionic (Li) conductivities. Such ”polymer electrolytes” offer widespread app...
متن کاملCharge redistribution mechanisms of ceria reduction.
Charge redistribution at low oxygen vacancy concentrations in ceria have been studied in the framework of the density functional theory. We propose a model to approach the dilute limit using the results of supercell calculations. It allows one to reproduce the characteristic experimentally observed behavior of composition versus oxygen pressure dependency. We show that in the dilute limit the c...
متن کاملFerroelectricity and Charge Ordering in Quasi One-Dimensional Organic Conductors
The family of molecular conductors TMTTF/TMTSF-X demonstrates almost all known electronic phases in parallel with a set of weak structural modifications of ‘anion ordering’ and mysterious ‘structureless’ transitions. Only in early 2000s their nature became elucidated by discoveries of a huge anomaly in the dielectric permittivity and by the NMR evidences for the charge ordering (disproportionat...
