چکیده
The Kagome lattice is an important fundamental structure in condensed matter physics for investigating the interplay of electron correlation, topology, and frustrated magnetism. Recent work on metals AV3Sb5 (A = K, Rb, Cs) family, has shown a multitude correlation-driven distortions, including symmetry breaking charge density waves nematic superconductivity at low temperatures. Here we study new metal Yb0.5Co3Ge3 find temperature-dependent kink resistivity that highly similar to behavior commensurate with in-plane structural distortion Co along doubling c-axis. space group found lower from P6/mmm P63/m below transition temperature, mirror planes C6 rotation, while gaining screw axis c-direction. At very temperatures, anisotropic negative magnetoresistance observed, which may be related This raises questions about types distortions nets their resulting physical properties

15 صفحه اولThe electronic properties of transition metal hydrogen complexes in silicon
The electrical levels of various combinations of transition metal-H defects in Si are calculated using spin-polarised local density functional cluster theory with an empirical correction. The shifts of these levels with H can be understood through a displacement and splitting of the gap manifold of states due to the impurity. Passive defects are identified.
متن کاملMETAL-NON METAL TRANSITIONS IN TRANSITION METAL COMPOUNDS.THE ELECTRONIC PHASE TRANSITIONS IN FeS AND NiS
FeS and NiS show first order phase transitions with a change in electronic structure at Ta = 415 K and Tt = 265 K respectively, the latter depending sensitively on non-stoichiometry in the form of nickel vacancies. Extensive experimental data on NiS is reviewed which shows that the low-temperature phase is a semimetallic itinerant-electron antiferromagnet and the high temperature phase a weakly...

متن کاملTwo-Dimensional Transition Metal Dichalcogenide Alloys: Stability and Electronic Properties.
Using density-functional theory calculations, we study the stability and electronic properties of single layers of mixed transition metal dichalcogenides (TMDs), such as MoS2xSe2(1-x), which can be referred to as two-dimensional (2D) random alloys. We demonstrate that mixed MoS2/MoSe2/MoTe2 compounds are thermodynamically stable at room temperature, so that such materials can be manufactured us...
