Theoretical study of the zero-gap organic conductor α-(BEDT-TTF)2I3
organic conductor α-(BEDT-TTF)2I3 massless Dirac fermion
2010/1/19
The quasi-two-dimensional molecular conductor α-(BEDT-TTF)2I3 exhibits anomalous transport phenomena where the temperature dependence of resistivity is weak but the ratio of the Hall coefficient at 10...
Experimental study of organic zero-gap conductor α-(BEDT-TTF)2I3
organic massless Dirac Fermions system transport phenomena zero mode
2010/1/19
A zero-gap state with a Dirac cone type energy dispersion was discovered in the organic conductor α-(BEDT-TTF)2I3 under high hydrostatic pressures. This is the first two-dimensional (2D) zero-gap stat...
Spatial mapping of electronic states in κ-(BEDT-TTF)2X using infrared reflectivity
organic conductor Mott transition phase separation
2010/1/19
We review our recent work on spatial inhomogeneity of the electronic states in the strongly correlated molecular conductors κ-(BEDT-TTF)2X. Spatial mapping of infrared spectra (SMIS) is used for imagi...
Organic metal (EDO-TTF)2PF6 with multi-instability
molecular conductor photo-induced phase transition multi-instability
2010/1/19
The multi-instability of the electronic structure of (EDO-TTF)2PF6, where EDO-TTF means ethylene-dioxytetrathiafulvalene, is reviewed. This complex showed the metal–insulator transition at 280 K assoc...
