Temperature-driven band inversion in Pb${}_{0.77}$Sn${}_{0.23}$Se: Optical and Hall-effect studies

Naween Anand, Zhiguo Chen, Sanal Buvaev +7

Optical and Hall-effect measurements have been performed on single crystals of Pb${}_{0.77}$Sn${}_{0.23}$Se, a IV-VI mixed chalcogenide. The temperature dependent (10--300 K) reflectan…
