Stripe and Short Range Order in the Charge Density Wave of 1T-Cu_{x}TiSe_{2}.
We study the impact of Cu intercalation on the charge density wave (CDW) in 1T-Cu_{x}TiSe_{2} by scanning tunneling microscopy and spectroscopy. Cu atoms, identified through density functional theory modeling, are found to intercalate randomly on the octahedral site in the van der Waals gap and to dope delocalized electrons near the Fermi level. While the CDW modulation period does not depend o...

متن کاملSliding charge-density wave in manganites.
Stripe and chequerboard phases appear in many metal oxide compounds, and are thought to be linked to exotic behaviour such as high-temperature superconductivity and colossal magnetoresistance. It is therefore extremely important to understand the fundamental nature of such phases. The so-called stripe phase of the manganites has long been interpreted as the localization of charge at atomic site...
متن کاملCharge-density-wave phase slip in NbSe3
We have studied the phase-slip process by which charge-density-wave (CDW) current is converted to single-particle current at electrical contacts. Transport and X-ray scattering measurements indicate that an excess voltage Vps dropped between current contacts induces a large static deformation of the CDW phase. The measured Vpsand temperature-dependent phase-slip rates are consistent with a mode...
متن کاملShort-range order in ternary aUoy semiconductors
Atom arrangements in IH-V ternary aHoy semiconductors are discussed using a thermodynamic analysis in which the elastic strain caused by mixing is considered as the mixing enthalpy. In calculating the strain energy, both bond-stretching and bond-angl.e distortion are taken into account, and Martin's microscopic elastic constants are used. The results show that there is a preference for ordering...
