The lab creates thin films and their interfaces in-house to explore quantum phenomena at low temperatures.
AboutAbout the lab
From thin films and interfaces to new physics
The Tsukazaki Lab fabricates thin films and the interfaces of stacked thin-film structures in-house, and studies their properties.
The lab has established techniques for forming high-quality interfaces in oxide heterostructures, and has extended its research to thin films of topological materials.
Using techniques for growing thin films in ultra-high vacuum, the lab focuses on quantum transport phenomena, typified by the quantum Hall effect.
Recently, it has also been working on superconductivity in nickel oxides and on thin-film interfaces of layered semiconductors.
Key terms
- Thin film
- An extremely thin film made by stacking atoms on a substrate. Depending on how the atoms are packed, it can be single-crystalline, polycrystalline, and so on.
- Interface
- The boundary between two solids, or between a solid and a liquid. The boundary between a solid and air or vacuum is called a surface.
- Quantum Hall effect
- A phenomenon in which, in a two-dimensional electron system at low temperature in a strong magnetic field, the ratio of the voltage perpendicular to the current (the Hall resistance) takes discrete values.

ResearchResearch themes
The lab is interested in thin-film chemistry and materials science for materials synthesis, and in interfacial properties and solid-state physics for observing phenomena. Using its own high-quality thin-film growth techniques, the lab creates new functional interfaces in-house, aiming to open up new physics such as quantum phenomena at low temperatures.
*Illustrative imageThin-Film Chemistry
Based on the idea that the balance between thermodynamic equilibrium and non-equilibrium determines thin-film quality, the lab grows thin films using several methods, including molecular beam epitaxy. It chooses the synthesis method best suited to each material.
*Illustrative imageInterfacial Properties
The interfaces formed by stacking thin films are a treasure trove of functionality. The lab studies the interfacial properties of quantum materials, including topological materials, and works both to understand them and to develop ways to control them.
*Illustrative imageExploring Quantum Properties at Low Temperatures
At low temperatures, where thermal fluctuations are small, the lab studies quantum phenomena such as superconductivity and the quantum Hall effect. It observes superconductivity in oxides and iron-based compounds, the anomalous Hall effect, and quantum transport of highly mobile electrons.
