Observation of high-temperature quantum anomalous Hall regime in intrinsic MnBiTe/BiTe superlattice
Haiming Deng, Zhiyi Chen, Agnieszka Wolos +11
The quantum anomalous Hall effect is a fundamental transport response of a topologically non-trivial system in zero magnetic field. Its physical origin relies on the intrinsically…
Mixed topological semimetals driven by orbital complexity in two-dimensional ferromagnets
Chengwang Niu, Jan-Philipp Hanke, Patrick M. Buhl +6
The concepts of Weyl fermions and topological semimetals emerging in three-dimensional momentum space are extensively explored owing to the vast variety of exotic properties that t…
Interface properties and built-in potential profile of a LaCrO/SrTiO superlattice determined by standing-wave excited photoemission spectroscopy
Shih-Chieh Lin, Cheng-Tai Kuo, Ryan B. Comes +14
LaCrO (LCO) / SrTiO (STO) heterojunctions are intriguing due to a polar discontinuity along (001), two distinct and controllable interface structures [(LaO)/(TiO)$^…
Functional Materials for Information and Energy Technology: Insights by Photoelectron Spectroscopy
Martina Müller, Slavomir Nemsak, Lukasz Plucinski +1
The evolution of both information and energy technology is intimately connected to complex condensed matter systems, the properties of which are determined by electronic and chemic…
On the nature of the spin polarization limit in the warped Dirac cone of the Bi2Te3
A. Herdt, L. Plucinski, G. Bihlmayer +6
The magnitude of electron spin polarization in topologically protected surface states is an important parameter with respect to spintronics applications. In order to analyze the wa…
