| Abstract | ||
| The effect of oxygen content on six samples of high temperature superconductor (HTS) Bi2Sr2CaCu2O8+δ (Bi:2212) was studied . As the sample oxygen content increases the value of condensation energy (which are calculated using the electronic specific heat and the entropy Ss of the superconducting phase) increases at the overdoped region . shows a maximum at the optimal doping (where and the hole concentration in CuO2 planes is ), at underdoped region decreases because of the effect of pseudo gap in the normal phase. | ||
