Evidence against a charge density wave on Bi(111)
The Bi(111) surface was studied by scanning tunneling microscopy (STM), transmission electron microscopy (TEM) and angle-resolved photoemission (ARPES) in order to verify the existence of a recently proposed surface charge density wave (CDW) [Ch. R. Ast and H. Höchst Phys. Rev. Lett. 90, 016403 (2003)]. The STM and TEM results to not support a CDW scenario at low temperatures. Furthermore, the ...
متن کاملThermodynamic evidence for valley-dependent density of states in bulk bismuth.
Electron-like carriers in bismuth are described by the Dirac Hamiltonian, with a band mass becoming a thousandth of the bare electron mass along one crystalline axis. The existence of three anisotropic valleys offers electrons an additional degree of freedom, a subject of recent attention. Here, we map the Landau spectrum by angle-resolved magnetostriction, and quantify the carrier number in ea...
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 کاملEvidence for the charge-density-wave nature of the stripe phase in manganites
Heat capacity and magnetization measurements strongly suggest that the onset of the stripe phase in La0.50Ca0.50MnO3, La0.48Ca0.52MnO3 and Pr0.48Ca0.52MnO3 is due to the formation of a charge density wave. The transition associated with the onset of the stripe phase is second order, and it can be well modelled as a Peierls transition (typically associated with chargedensity-wave formation) in a...
