ELECTRICAL PROPERTIES AND BAND STRUCTURE IN Pb1-xSnxTe
Strong evidence for the existence of two valence bands in Pb0.7Sn0.3Te and Pbo.sSno.sTe is inferred from the observation of a kink in the variation of the Hall ratio R ~ O O ~ K I R ~ ~ O O K , as a function of hole concentration. This existence is also supported by the fact that the variation of the Seebeck coefficient as a function of hole concentration exhibits a minimum. Moreover, non parab...
متن کاملDirac Landau Level Spectroscopy in Pb1−xSnxSe and Pb1−xSnxTe across the Topological Phase Transition: A Review
Topological crystalline insulators (TCIs) are topological materials that have Dirac surface states occurring at crystalline symmetric points in the Brillouin zone. This topological state has been experimentally shown to occur in the lead–tin salts Pb1−xSnxSe and Pb1−xSnxTe. More recent works also took interest in studying the topological phase transition from trivial to non-trivial topology tha...
متن کاملMicrostructure Characterization and Bulk Properties of Disordered Two-Phase Media
A general formalism is developed to statistically characterize the microstructure of porous and other composite media composed of inclusions (particles) distributed throughout a matrix phase (which, in the case of porous media, is the void phase). This is accomplished by introducing a new and general n-point distribution function HA and by deriving two series representations of it in terms of t...

Corrigendum: Observation of a topological crystalline insulator phase and topological phase transition in Pb1−xSnxTe
In Fig. 2a and d of this Article, a uniform background subtraction was applied to the ARPES low-energy electronic structure measurements. In Fig. 2d, this background subtraction unintentionally was only applied to the central part of the figure. This affected the noise in the background but not the meaningful signal data features discussed in the paper, and therefore does not affect any conclus...
متن کاملMassive and massless Dirac fermions in Pb1−xSnxTe topological crystalline insulator probed by magneto-optical absorption
Dirac fermions in condensed matter physics hold great promise for novel fundamental physics, quantum devices and data storage applications. IV-VI semiconductors, in the inverted regime, have been recently shown to exhibit massless topological surface Dirac fermions protected by crystalline symmetry, as well as massive bulk Dirac fermions. Under a strong magnetic field (B), both surface and bulk...
