As two-dimensional structural systems, thin films exhibit a wide variety of physical properties that cannot be realised in bulk materials due to their reduced dimensionality and interfacial effects.
From a materials synthesis viewpoint, the kinetic energy of the constituent elements during thin-film growth plays a crucial role in crystal formation. Consequently, materials that are challenging to synthesise in bulk form can sometimes be produced as high-quality samples when fabricated as thin films.
In this way, thin films represent an exceptional research platform, enabling unconventional developments in physical property exploration and materials synthesis and providing fertile ground for advancing new frontiers in condensed matter physics. Focusing on the unique characteristics and possibilities of thin-film systems, our research is based on following approaches:

1) Microfabrication of thin films and development of high-performance devices;
2) Exploration of interfacial properties in thin films and their control by electric fields;
3) Thin-film fabrication of materials that are difficult to synthesise as bulk crystals.
