Abstract
We have successfully fabricated high quality YBa2Cu3O7 microwave “T” resonators on YSZ buffered P-type (100) oriented 53-56 Ω- cm silicon. The 40 to 50 nm thick yttria-stabilized zirconia buffer layer was deposited by pulsed dc magnetron sputtering at 830°C. The 250 to 400 nm thick YBa2Cu3O7 film was deposited using laser ablation at 760°C. Results include Q values in excess of 20,000 at 3.8 GHz on a coplanar “T” resonator at temperatures below 50 K
