Oxide thin film and device fabrication
- Using the PLD (Pulsed Laser Deposition) method, epitaxial metal oxide thin films are produced on a single crystal substrate.
- The properties of the metal oxide thin film are analyzed using equipment such as TEM (Transmission Electron Microscope), SEM (Scanning Electron Microscope), XPS (X-ray Photoelectron Spectroscopy), XRD (X-ray Diffraction), and PPMS (Physical Properties Measurement System).
Topological Quantum Devices
- Physically one-dimensional topological insulator nanowires exhibit quantum confinement and quantum interference phenomena at very low temperatures, displaying characteristics typical of low-dimensional quantum systems.
- Investigating the properties of these nanostructures under varying conditions of temperature, magnetic fields, and voltage helps advance our understanding of low-dimensional quantum systems.
Infinite-layer Super conductor
- Nickel strontium niobate (NSNO) thin films, as well as high-temperature superconductors like yttrium barium copper oxide (YBCO), are fabricated and analyzed.
- Insulating materials are deposited between the high-temperature superconductor thin films to create Josephson junctions, enabling the development of quantum devices.
