Current-voltage characteristics of charge-ordered organic crystals.
The current-voltage characteristics of layered organic crystals theta-(BEDT-TTF)2MZn(SCN)4 (M = Cs, Rb) follow the power law with a large exponent (e.g., 8.4 at 0.29 K for M = Cs) over a wide range of currents in the low-temperature insulating state. The power-law characteristics are attributed to electric field-induced unbinding of electron-hole pairs that are thermally excited in the backgrou...
متن کاملInfrared and Raman Studies of Charge Ordering in Organic Conductors, BEDT-TTF Salts with Quarter-Filled Bands
This paper reviews charge ordering in the organic conductors, β′′-(BEDT-TTF) (TCNQ), θ-(BEDT-TTF)2X, and α-(BEDT-TTF)2X. Here, BEDT-TTF and TCNQ represent bis(ethylenedithio)tetrathiafulvalene and 7,7,8,8-tetracyanoquinodimethane, respectively. These compounds, all of which have a quarter-filled band, were evaluated using infrared and Raman spectroscopy in addition to optical conductivity measu...
متن کاملThe angular dependent magnetoresistance in α-(BEDT- TTF)2KHg(SCN)4
– In spite of extensive experimental studies of the angular dependent magnetoresistance (ADMR) of the low temperature phase (LTP) of α-(BEDT-TTF)2KHg(SCN)4 about a decade ago, the nature of LTP remains elusive. Here we present a new study of ADMR of LTP in α−(ET)2 salts assuming that LTP is unconventional charge density wave (UCDW). In the presence of magnetic field the quasiparticle spectrum i...
متن کاملNovel Charge Order and Superconductivity in Two-Dimensional Frustrated Lattice at Quarter Filling
Motivated by the various physical properties observed in θ-(BEDT-TTF)2X, we study the ground state of extended Hubbard model on two-dimensional anisotropic triangular lattice at 1/4-filling with variational Monte Carlo method. It is shown that the nearest-neighbor Coulomb interaction enhances the charge fluctuation and it induces the anomalous state such as charge-ordered metallic state and the...

A coexistent system of itinerant and Iocalized electrons was prepared and the magnetic properties of bath electron~ were investigated. a-(BEDT-TTF)2CSCOjSCN)4 (abbreviated as the Csco Salt ), a-(BEDT-TTF)2RbCOjSCN)4 (the Rbco Salt), and a"-(BEDT-TTF)2 Ki 4Co(SCN)4 (the KCO Salt), undergo metal-insulator transitions at 10 K, 190 K, and 130 K. respectively. The ESR measurement of the Rbco sait in...
