| Research Abstract |
Dependence of the Tc and Pc of the pressure-induced superconductorβ-(BDA-TTP) 2I3 on the orientation of uniaxial strain has been investigated. Based on the overlap between the upper and lower bands in the energy dispersion curve, the pressure orientation is thought to change the half-filled band to the quarter-filled one. The observed variations in Tc and Pc are explained by considering the degree of application of the pressure and the degree of contribution of the effective electronic correlation at uniaxial strains within the conducting donor layer. Analyses of crystal structures have been carried out under the a-axis, b-axis, c-axis strains
