Atomic-Scale investigations of MnTe with Scanning Tunneling Microscopy

MnTe has attracted considerable attention as a platform for exploring altermagnetism—a novel form of magnetism combining antiferromagnetic compensation with anisotropic spin-polarized band structures. Recently, the g-wave altermagnetism of MnTe has been demonstrated by angle resolved photoemission, inelastic neutron scattering, and transport studies. Scanning tunneling microscopy and spectroscopy (STM/S) provides a powerful local probe that enables atomic-scale investigations of the surface morphology, defect structure, and local density of states. Here we present STM/S results from the (0001) surface of cleaved single crystal MnTe. We report atomically resolved images and surface dependent measurements of the local density of states, enabling real-space mapping of the electronic structure.
