Topological semimetals have recently attracted extensive research interests as host materials to condensed matter physics counterparts of Dirac and Weyl fermions originally proposed in high energy physics. These with linear dispersions near the or points obey Lorentz invariance, chiral anomaly leads novel quantum phenomena such negative magnetoresistance. The invariance is, however, not necessarily respected physics, thus Lorentz-violating type-II strongly tilted cones can be realized...
Topological semimetals have attracted extensive research interests for realizing condensed matter physics counterparts of three-dimensional Dirac and Weyl fermions, which were originally introduced in high energy physics. Recently it has been proposed that type-II semimetal can host a new type fermions break Lorentz invariance therefore does not counterpart Here we report the electronic structure quality PtSe$_2$ crystals to provide direct evidence existence fermions. A comparison crystal,...
The generally accepted view that spin polarization in non-magnetic solids is induced by the asymmetry of global crystal space group has limited search for spintronics materials mainly to non-centrosymmetric materials. In recent times it been suggested originates fundamentally from local atomic site asymmetries and therefore centrosymmetric may exhibit previously overlooked polarizations. Here, using spin- angle-resolved photoemission spectroscopy, we report observation helical texture...
Atomically thin PtSe2 films have attracted extensive research interests for potential applications in high-speed electronics, spintronics and photodetectors. Obtaining high quality, single crystalline with large size is critical. Here we report the first successful layer-by-layer growth of quality by molecular beam epitaxy. from 1 ML to 22 been grown characterized low-energy electron diffraction, Raman spectroscopy X-ray photoemission spectroscopy. Moreover, a systematic thickness dependent...
We report the electronic structure of CuTe with a high charge density wave (CDW) transition temperature ${\mathrm{T}}_{c}=335\text{ }\text{ }\mathrm{K}$ by angle-resolved photoemission spectroscopy. An anisotropic gap maximum value 190 meV is observed in quasi-one-dimensional band formed Te ${p}_{x}$ orbitals. The CDW can be filled increasing or electron doping through situ potassium deposition. Combining experimental results calculated scattering susceptibility and phonon dispersion, we...
Atomically thin transition metal dichalcogenide films with distorted trigonal (1T$^\prime$) phase have been predicted to be candidates for realizing quantum spin Hall effect. Growth of 1T$^\prime$ film and experimental investigation its electronic structure are critical. Here we report the 1T$^\prime$-MoTe$_2$ grown by molecular beam epitaxy (MBE). depends critically on substrate temperature, successful growth is indicated streaky stripes in reflection high energy electron diffraction sharp...
