2014 Theories cannot actually predict the value and the T-dependence of the electronic spin resonance linewidth of organic conductors. To compensate this difficulty, most of the experiments have been carried out on families of compounds. In order to reduce the number of parameters, we have modified on the same compound (TTF-TCNQ) the interchain coupling by introducing chain breakings. We observ...
The interest in graphene (a carbon monolayer) adsorbed on metal surfaces goes back to the 60's, long before isolated was produced laboratory. Owing carbon-metal interaction and lattice mismatch between monolayer surface, usually adopts a rippled structure, known as moiré, that confers it interesting electronic properties not present graphene. These moiré structures can be used versatile templat...
Silver-tetracyanoquinodimethane(Ag-TCNQ) nanostructured arrays with different morphologies were grown by an organic vapor-transport reaction under different conditions. The field emission properties of nanostructured arrays were studied systematically. Their morphology and crystal structure were characterized by SEM and XRD, respectively. It was found that the field emission properties were str...
We use midinfrared pulses with stable carrier-envelope phase offset to drive molecular vibrations in the charge transfer salt ET-F_{2}TCNQ, a prototypical one-dimensional Mott insulator. We find that the Mott gap, which is probed resonantly with 10 fs laser pulses, oscillates with the pump field. This observation reveals that molecular excitations can coherently perturb the electronic on-site i...
0.1016/j.nanoen.2 lsevier Ltd. All rig thor. [email protected] ( Abstract We demonstrated the efficiency of a solution-processed planar heterojunction organometallic trihalide perovskite solar cell can be increased to 17.5% through doping the hole transporting layer for reducing the resistivity. Doped Poly(triaryl amine) (PTAA) by 2,3,5,6-Tetrafluoro7,7,8,8-Tetracyanoquinodimethane (F4-TCNQ) reduc...
