| Outline of Final Research Achievements |
To examine electronic states of type II Weyl semimetals, we have performed spectroscopic-imaging scanning tunneling microscopy of beta-MoTe2, which is a candidate material of type II Weyl semimetal. The electronic states we observed can be classified into two groups, indicating that two kinds of surfaces originating from the polar crystal structure of beta-MoTe2 are resolved. In both cases, the electronic states exhibit complicated structures especially above the Fermi energy. Details of the electronic states can be identified by comparing the experimental data and the theoretical simulation of quasiparticle interference.
