Charge modulation in two-dimensional compounds

Although the first measurements demonstrating charge modulation were performed forty years ago, many open questions are now the matter of intense research. In the first part of this short review, some recent results obtained on transition metal dichalcogenides (MX sub(2)) compounds will be presented...

Summary:Although the first measurements demonstrating charge modulation were performed forty years ago, many open questions are now the matter of intense research. In the first part of this short review, some recent results obtained on transition metal dichalcogenides (MX sub(2)) compounds will be presented such as: mechanism of the Peierls transition, effect of strong electron-phonon coupling, soft mode in the phonon dispersion, chirality effects,...Charge order, ferroelectricity, frustration, glassiness in organic 2D systems will be the subject of the second part. The third part will be devoted to describe the properties of a new family of 2D compounds, namely rare earth tritellurides, in which the size of the rare earth determine the charge density wave transition temperature.
