2016年6月2日 · Here we report that superconductivity emerges upon Se doping in CDW conductor ZrTe 3 when the long range CDW order is gradually suppressed. Superconducting critical temperature Tc (x) in...

2020年1月7日 · Charge density waves (CDWs) in the cuprate high-temperature superconductors have evoked much interest, yet their typical short-range nature has raised questions regarding the role of disorder. Here...

2021年6月23日 · Here, we visualize the impurity pinning evolution of the CDW in $ {\mathrm {ZrTe}}_ {3}$ using the variable temperature scanning tunneling microscopy. At low temperatures, we observe a quasi-1D incommensurate CDW modulation moderately correlated to the impurity positions, indicating a weak impurity pinning.

Impurity pinning has long been discussed to have a profound effect on the dynamics of an incommensurate charge density wave (CDW), which would otherwise slide through the lattice without resistance. Here, we visualize the impurity pinning evolution of the CDW in ZrTe3 using the variable temperature scanning tunneling microscopy.

2021年5月6日 · Impurity pinning has long been discussed to have a profound effect on the dynamics of an incommensurate charge density wave (CDW), which would otherwise slide through the lattice without resistance. Here we visualize the impurity pinning evolution of the CDW in ZrTe3 using the variable temperature scanning tunneling microscopy (STM).

Zirconium tritelluride (ZrTe3) is a semimetal exhibiting charge density wave (CDW) at around 60-70K and superconducting phenomena (Tc~2-5K). It belongs to the group-IV transition metal trichalcogenides. Our crystals have been engineered to attain rather low record defect density (1E9-1E10cm-2) to yield environmentally stable ZrTe3 crystals.

2019年2月24日 · In this paper, we present high resolution laser-based angle-resolved photoemission spectroscopy (ARPES) study on the three-dimensional (3D) hole-like Fermi surface around the Brillouin zone center in a prototypical qusi-one-dimensional CDW and superconducting system ZrTe3.

2015年2月7日 · Here we show that phonon-electron coupling is also important for the CDW formation in a model quasi-1D system ZrTe$_3$. Our joint experimental and computational study reveals that particular lattice vibrational patterns possess exceedingly strong coupling to the conduction electrons, and are directly linked to the lattice distortions associated ...

2019年5月15日 · We report electrical and thermal transport properties of polycrystalline ZrTe 3. The polycrystalline sample shows semiconducting behavior in contrast to the established semi-metallic character of the compound.

Here we report that superconductivity emerges upon Se doping in CDW conductor ZrTe3 when the long range CDW order is gradually suppressed. Superconducting critical temperature Tc(x) in...
