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 کاملEffect of Spaceship Orbital Transfer on Solution Convection during Protein Crystal Growth under Microgravity
Detailed numerical analysis is presented for the effect of spaceship orbital transfer on solution convection during protein crystal growth under microgravity. The results show that the flow and mass transfer during protein crystal growth are unsteady in the process of orbital transfer. For the case of quasi-steady acceleration, the flow is so weak that the effect of flow on concentration field ...
متن کاملA pressure-induced topological phase with large Berry curvature in Pb1−xSnxTe
The picture of how a gap closes in a semiconductor has been radically transformed by topological concepts. Instead of the gap closing and immediately reopening, topological arguments predict that, in the absence of inversion symmetry, a metallic phase protected by Weyl nodes persists over a finite interval of the tuning parameter (for example, pressure P). The gap reappears when the Weyl nodes ...
