Herringbone structure in GeTe-based thermoelectric materials
TL;DR: In this paper, the microstructure of GeTe-based thermoelectric materials was investigated using transmission electron microscopy, where the authors proposed a parallelepiped domain unit surrounded by (0, 0, 1), (1, 1, 0 ) and ( 1 1 1, 0 ) planes.

Z 3 -vestigial nematic order due to superconducting fluctuations in the doped topological insulators Nb x Bi 2 Se 3 and Cu x Bi 2 Se 3
Chang-woo Cho,Junying Shen,Junying Shen,Jian Lyu,Jian Lyu,Omargeldi Atanov,Qianxue Chen,Seng Huat Lee,Yew San Hor,Dariusz Jakub Gawryluk,Ekaterina Pomjakushina,Marek Bartkowiak,Matthias Hecker,Jörg Schmalian,Rolf Lortz +14 more
TL;DR: The authors show that nematic superconductivity in electron-doped Bi2Se3 gives way to a vestigial nematic phase driven by fluctuating Cooper pairs.
