thin films were deposited by a pulsed laser deposition technique on amorphous substrates, e.g., for demonstration, glass substrates were used. Various interlayers were introduced to enhance the superconducting properties. Detailed microstructural characterizations including X-ray diffraction and cross-sectional transmission electron microscopy were conducted to verify the film quality. The results indicated the highly textured FeSe
