A scaled-up hybrid physical-chemical vapor deposition (HPCVD) method has been developed to fabricate large-area high-quality magnesium diboride (MgB2) thin films. The 2-in-diameter MgB2 thin films on sapphire (0001) show uniform superconducting properties, including Tc ~ 39 K, residual-resistivity ratio ~ 14, and Jc (4.2 K) ~ 107 A/cm2. X-ray diffraction showed that the films are epitaxial with c-axis normal to the film surface. The film properties are uniform across the 2-in substrate.
