Superconducting MgB2 Thin Films withTc ≈ 39 K Grown by Pulsed Laser Deposition
-
Abstract
Superconducting MgB2 thin films were fabricated on Al2O3(0001) substrates under an ex situ processing conditions. Boron thin films were deposited by pulsed laser deposition followed by a post-annealing process. Resistance measurements of the deposited MgB2 films show Tc of ～39 K, while scanning electron microscopy and x-ray diffraction analysis indicate that the films consist of well-crystallized grains with a highly c-axis-oriented structure.
