Article Synopsis
- Researchers used advanced momentum microscopy to investigate the electronic properties of the topological Dirac semimetal 1T-ZrTe, specifically focusing on the behavior of its Dirac cone above the Fermi level.
- They discovered the role of different scattering processes in how electrons relax, observing important electron-hole interactions and finding that the electrons' lifetime correlates linearly with their excess energy.
- The study offers new insights into the excited state dynamics of 1T-ZrTe, contributing to the understanding of ultrafast electron behaviors in 3D topological materials.
Two-dimensional (2D) van der Waals (vdW) ferromagnetic metals FeGeTe with = 3-5 have raised significant interest in the scientific community. FeGeTe shows prospects for spintronic applications since the Curie temperature has been reported near or higher than 300 K. In the present work, epitaxial FeGeTe (FGT) heterostructures were grown by Molecular Beam Epitaxy (MBE) on insulating crystalline substrates.

Here, we demonstrate the growth of Bi films by molecular beam epitaxy on 2D-HfTetemplate. At the initial stage of Bi deposition (1-2 bilayers, BL), both the pseudocubic Bi(110) and the hexagonal Bi(111) phases are formed.
