Report

Anisotropic positive linear and sub-linear magnetoresistivity in the cubic type-II Dirac metal Pd$_3$In$_7$

Autor: Savvidou, Aikaterini Flessa, Ptok, Andrzej, Sharma, G., Casas, Brian, Clark, Judith K., Li, Victoria M., Shatruk, Michael, Tewari, Sumanta, Balicas, Luis

We report a transport study on Pd$_3$In$_7$ which displays multiple Dirac type-II nodes in its electronic dispersion. Pd$_3$In$_7$ is characterized by low residual resistivities and high mobilities, which are consistent with Dirac-like quasiparticles

Whereas electron-phonon scattering typically relaxes the electron's momentum in metals, a perpetual exchange of momentum between phonons and electrons conserves total momentum and can lead to a coupled electron-phonon liquid with unique transport pro

Complex Dirac-like Electronic Structure in Atomic Site Ordered Rh3In3.4Ge3.6

Autor: Savvidou, Aikaterini Flessa, Clark, Judith K., Wang, Hua, Wei, Kaya, Choi, Eun Sang, Mozaffari, Shirin, Qian, Xiaofeng, Shatruk, Michael, Balicas, Luis

Publikováno v: Chem. Mater. (2021)

We report the synthesis via an indium flux method of a novel single-crystalline compound Rh3In3.4Ge3.6 that belongs to the cubic Ir3Ge7 structure type. In Rh3In3.4Ge3.6, the In and Ge atoms choose to preferentially occupy, respectively, the 12d and 1
