Abstract
MOCVD is a promising method for preparation of high-quality thinfilms of superconducting and dielectric oxides. In order to improve the reproducibility of MOCVD process, we propose in situ monitoring of growth processes. An ultrasonic transducer is introduced to monitor and control the concentration of precursor gas supply rate. Spectroscopic ellipsometry is proved to be effective for realtime characterization of the quality of superconducting thinfilms.
