ANGULAR DEPENDENCE OF D-WAVE SUPERCONDUCTIVITY IN IRRADIATED CUPRATES

Abstract

We subject the minimized d-wave energy provided for by electromagnetic (e.m) radiation to the thermal activation factor and proceed to obtain transition temperature dependence on zenith and azimuthal angle of the d-electrons in superconducting cuprates. A linear relation of Tc and zenith angle ∅ is revealed. For ∅ = 1.68 , Tc=300K is achieved, providing a promising possibility of room temperature superconductivity. A non-linear increase in T c is observed when the azimuthal angle is reduced to 0.4 radians. Between 0 − 0.4 radians, the highest T c achievable in YBCO and HgBa2Ca2Cu3O8 is 160 K. The angular part of a wave function of an electron system is responsible for orbital orientation. Hence orbital orientation of the d-electron, to a great extend, influences Tc of high temperature superconducting cuprates.
