Electronic tuning of the soft-phonon transport anomaly in Ta $_{2}$ Ni(S $_{x}$ Se $_{1 - x}$ ) $_{5}$

Yuan-Shan Zhang, Masahiko Isobe, Hidenori Takagi +1

Ta $_{2}$ NiSe $_{5}$ continues to be investigated for its phase transition at $T_{c}$ = 326 K, where it develops both an electronic gap and a distortion of its Ta/Ni chains. One i…

Substrate tuning of the structural and electronic transition in thin flakes of the excitonic insulator candidate Ta $_{2}$ NiSe $_{5}$

Yuan-Shan Zhang, Zichen Yang, Chuanlian Xiao +4

Ta $_{2}$ NiSe $_{5}$ continues to draw interest for its 326 K phase transition, whose dual electronic and structural nature reflects a complex interplay of electron-hole (excitonic) and…

Thermal transport signatures of the excitonic transition and associated phonon softening in the layered chalcogenide Ta $_{2}$ NiSe $_{5}$

Yuan-Shan Zhang, Jan A. N. Bruin, Yosuke Matsumoto +2

The layered compound $T a_{2} NiS e_{5}$ is a quasi-one-dimensional and narrow-gap semiconductor, which is proposed to undergo a transition to an excitonic insulator at $T_\mathr…
