Outline of Final Research Achievements

To date, breaking the inversion symmetry becomes an important factor, which introduce various peculiar feature in materials like Weyl semimetals. However, it has been impossible to induce broken inversion symmetry intentionally. In this project, I developed a furnace which works in the superconducting magnet. A Dirac semimetal TlBi(S0.5Se0.5)2 is tried to be grown in the magnetic fields, but no peculiar feature has been observed yet. The developed method will be applicable for growth of bulk crystals and annealing of thin films, etc.
