    We have developed a low-temperature, high-magnetic-field scanning tunneling microscope (STM) combined with pulsed laser deposition (PLD), and studied the electronic structures of homoepitaxial thin film surfaces of SrTiO3(001). Thin film thicknesses were monitored during depositions using a reflection high-energy electron diffraction, and the samples were investigated by using the STM without exposing the sample surfaces to air. Scanning tunneling spectroscopy (STS) mapping reveals a number of defects that can be categorized into three feature-specific types. The development of this STM-PLD system opens up a way to investigate extraordinary and inhomogeneous electronic structures in complex oxide thin films, heterostructures and nanostructures.
