Abstract
MgB2 thin films with the Tc above 38 K have been fabricated using molecular beam epitaxy (MBE) at the growth temperature below 300°C. The Tc of 38.2 K was obtained in 1.3-μm-thick MgB 2 films formed on SiC substrates with AlN buffer layers. The T c is comparable to those of MgB2 single crystals and the highest among MgB2 films fabricated below 500°C. Increase of the film thickness of MgB2 above 1 μm was the key point to obtain high-quality films at low growth temperature.
