| Outline of Final Research Achievements |
In this project, we have intensively studied transport characteristics of artificial topological-material nanostructures by using semiconductor heterostructures and low-dimensional structures. Particularly we have developed novel topological quantum phenomena that cannot be seen in bulk materials and provided design concepts for novel nanostructured devices with topological materials. Specific results include (1) dynamics and non-equilibrium phenomena in chiral edge states in quantum Hall systems, (2) controlling helical edge states in quantum spin Hall systems, (3) spin transport based on spin-orbit locking and Weyl semimetals, (4) elemental technologies for controlling fractional charges in fractional quantum Hall systems, and (5) experimental and theoretical works for detecting Majorana quasiparticles. These results would provide physical understandings of topological quasiparticles and applications of topological-material nanostructures.
