Novel electronic states of organic conductors under uniaxial stress or uniaxial strain

Uniaxial compression is expected to play a useful role in changing electronic properties of organic conductors because of the low-dimensional electronic structures. To control the intermolecular distance only along some specific axis, we developed the method of causing uniaxial strains along any direction. Novel electronic states were found in α-(BEDT-TTF)2KHg(SCN)4 and α-(BEDT-TTF)2I3 by controlling the direction of the uniaxial strain.
