To visualise the morphologic changes of a growing spiral pyramid, a mathematical model was developed and implemented in an algorithm that can loop through the sequential time-frames in a growth sequence. The algorithm simulates growth of spiral pyram

We report the in-plane anisotropy of the onset of superconductivity in the organic superconductor (TMTSF) 2 ClO 4 in magnetic fields H accurately aligned to the most conductive ab ′ plane. We revealed that the rapid increase of the onset fields at

The influence of non magnetic impurities on the superconductivity of the quasi-one dimensional organic conductor (TMTSF)2ClO4 is investigated. Non magnetic impurities are added through the substitution of up to 3% of the ClO4 anions by ReO4 anions. T

The electronic properties, carrier injection, and transport into poly(9,9-dioctylfluorene) (PFO), PFO end-capped with hole-transporting moieties (HTM), PFO–HTM, and PFO end-capped with electron-transporting moieties (ETM), PFO–ETM, were investiga

We report accurate Hall effect measurements performed in the normal phase of the quasi-one-dimensional organic conductor $(\mathrm{TMTSF}{)}_{2}{\mathrm{PF}}_{6}$ at ambient pressure. The Hall coefficient is found to be strongly temperature dependent

We present c-axis resistivity measurements performed on the organic conductors and under pressure. The aim is to probe the density of states of quasi-one dimensional compounds the high temperature properties of which are those of a Luttinger liquid.

The polarized optical reflectance of the quasi-one-dimensional organic conductor (TMTSF) 2 ClO 4 has been measured along the chain axis from the far-infrared (∼8 meV) to the visible (∼1 eV) at temperatures between 10 and 300 K. A self-consistent

Non magnetic impurities substitution is a method to check the microscopic origin of superconductivity. In (TMTSF) 2 ClO 4 , we substitute a small fraction of the ClO 4 anions by ReO 4 . The anion ordering temperature is shown to be unaffected by allo

Conductivity and permittivity ϵ of (TMTSF) 2 PF 6 have been measured at low frequencies of (10 2 –10 7 Hz) at low temperatures below the spin-density wave (SDW) transition temperature T p . The temperature dependence of the conductivity shows a de

We report on specific heat measurements of the SDW compound (TMTSF)2PF6 between 2 and 25 K, performed by two different techniques. We discuss the two successive transitions which occur in this T-range: the SDW ordering transition at T = 12.1 K, and a
