Studies of the static magnetic susceptibility and microwave properties of tetrathiofulvalinium-tetracyanoquinodimethane
… Tetrathiofulvalinium-Tetracyanoquinodimethane (TTF-TCNQ) was measured using the Faraday method. Particular attention was paid to the region below 60 K in order to investigate the metal-to-insulator transformation this material undergoes. Anomalies in the susceptibility were apparent near 55 K …

Scanning electron microscope technique for measuring electrical conductivity: Application to tetrathiafulvalene-tetracyanoquinodimethane
… tetrathiafulvalenetetracyanoquinodimethane (TTF-TCNQ) is reported. A movable current sour(:e provided by the electron beam of a scanning electron microscope is used to map out the potential distribution on crystal faces containing the a-b crystallographic axes. Silver paint contacts are used …

Electrical properties of some low-dimensional compounds
… compounds studied in this work are ethylated TTF-TCNQ, another pseudo-one-dimensional compound, . and IT-Til+x Se2, a two-dimensional compound. Electrical conductivity and heat capacity measurements on TTF-DETCNQ reveal a metal-insulator transition at III ± 1 K, a temperature higher than the …

Investigation on the Morphology of Charge-Transfer Complexes in Low Density Polyethylene
… In this study, the effect of tetrathiafulvalene (TTF) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) CTC crystallites of various shapes and sizes on composite mechanical properties was investigated in an LDPE (low density polyethylene) polymer matrix. The CTC morphology was selectively controlled via …

Density-functional theory and beyond for organic electronic materials
… Arbeit zeigt anhand des Tetrathiafulvalen-(TTF)-Tetracyanoquinodimethan-(TCNQ)-Komplexes, dass beide Aspekte bei schwach wechselwirkenden Molekülen berücksichtigt werden müssen, weil ansonsten Artefakte in der Beschreibung des Elektronentransfers und der Bindungskurve auftreten. Um diese …

Strong electronic correlations in low-dimensional systems
… We apply this method to two organic crystals: TTF-TCNQ and (BEDT-TTF)_2 I_3. Having the parameters of the former we solve a long standing problem in the interpretation of its spectra. One of the most successful methods to treat strongly correlated systems is DMFT. It provides a good …
