Thermal diffusivity measurement of YBa2Cu3O7-x thin film with a picosecond thermoreflectance technique uri icon

abstract

  • The thermal diffusivity of YBa2Cu3O7-x (YBCO) film was measured using the optical pump-probe method. A theoretical finite-difference model was employed to calculate the diffusivity value, and the best fit for the c-axis oriented YBCO film showed an average thermal diffusivity of 0.25 0.05 mm2 s-1. The obtained result is compared to previous reports measured using various methods. 2010 Elsevier B.V. All rights reserved.
