Nonlinear conduction of sliding electronic crys - tals : Charge and Spin Density Waves

چکیده
A model of local metastable states (MSs) due to the pinning induces plastic deformations allows to describe the nonlinear I − V curves in sliding density waves (DW). With increasing DW velocity v, the MSs of decreasing lifetimes τ ∼ 1/v are accessed. The characteristic second threshold field is reached when the shortest life time configurations are accessed by the fast moving DW. Thus the DW works as a kind of a " linear accelerator " testing virtual states.

First-principles study on the electronic structure of Thiophenbithiol (TBT) on Au(100) surface
First principle calculations were performed using Density functional theory within the local spin density approximation (LSDA) to understand the electronic properties of Au(100)+TBT system and compare the results with Au(100) and bulk Au properties. Band structure, the total DOS and charge density for these materials are calculated. We found that the HOMO for Au(100)+TBT becomes broader than Au...

Non-linear electrical response in a charge/orbital ordered Pr 0.63 Ca 0.37 MnO 3 crystal : the charge density wave analogy. Abstract Non-linear conduction in a charge-ordered manganese oxide Pr 0.63 Ca 0.37 MnO 3 is reported. To interpret such a feature, it is usually proposed that a breakdown of the charge or orbitally ordered state is induced by the current. The system behaves in such a way t...
متن کاملStrong-Pinning Effects in Low-Temperature Creep: Charge-Density Waves in TaS3
Nonlinear conduction in the quasi-one dimensional conductor o-TaS3 has been studied in the low-temperature region down to 30 mK. It was found that at temperatures below a few Kelvins the current-voltage (I-V) characteristics consist of several branches. The temperature evolution of the I-V curve proceeds through sequential freezing-out of the branches. The origin of each branch is attributed to...
