Direct Observation of Strongly Tilted Dirac Points at General Positions in the Reciprocal Space
Yangsong Ye, Shijie Kang, Jiusi Yu +7
Type-II Dirac points (DPs), which occur at the intersection of strongly tilted and touching energy bands, exhibit many intriguing physical phenomena fundamentally different from th…
