Growth of Altermagnetic α-MnTe Films: Substrate Variation and Surface Modification
M. Dittmar, L. Hirnet, H. Haberkamm +10
Manganese telluride (MnTe) in its hexagonal α-MnTe crystal structure has evolved as one of the altermagnet workhorse materials. The synthesis of MnTe thin films is highly relevant…
The nexus between negative charge-transfer and reduced on-site Coulomb energy in a correlated topological metal CoTe
A. R. Shelke, C. -W. Chuang, S. Hamamoto +7
The layered transition metal dichalcogenide (TMD) CoTe is a topological Dirac Type-II metal. However, the Co -bands in CoTe do not exhibit the expected correlation…
Role of on-site Coulomb energy and negative-charge transfer in a Dirac semi-metal NiTe
A. R. Shelke, C. -W. Chuang, S. Hamamoto +7
Angle-resolved photoemission spectroscopy (ARPES) combined with band structure calculations have shown that the layered transition metal dichalcogenide(TMD) NiTe is a type-II D…
Unusual band evolution and persistence of topological surface states in high-T_C magnetic topological insulator
K. Hori, S. Souma, C. -W. Chuang +12
Understanding the mechanism of ferromagnetism in ferromagnetic topological insulators (TIs) is a key to realize exotic time-reversal-symmetry-broken quantum phases. However, electr…
