We describe the setting-up and the performance of a newly developed combined system of combinatorial laser molecular beam epitaxy and low-temperature ultra-high vacuum scanning tunneling microscopy. This facility aims at accelerating the materials research in a highly efficient way, by advanced high-throughput film synthesis techniques and subsequent fast characterization of surface morphology and electronic states. During five years efforts, the system has exhibited good stability on both combi-film deposition and STM measurements, and decidedly appreciated advantages in both exploring new materials and investigating novel physical phenomenon.
