Dichalcogenides

Layer-type Dichalcogenides.— The unique photoelectrochemical properties of the layer-type dichalcogenides were first pointed out by Tributsch, and in the Faraday Discussion he reviews this group of compounds. Table 2 lists some of the [Pg.589]

Although the layer-type dichalcogenides are stable even under the most aggressive conditions, their performance as photoelectrodes is limited by surface recombination at steps in the crystal surface. Lewerenz et have discussed [Pg.590]

As an indication of the types of infonnation gleaned from all-electron methods, we focus on one recent approach, the FLAPW method. It has been used to detennine the band stmcture and optical properties over a wide energy range for a variety of crystal stmctures and chemical compositions ranging from elementary metals [ ] to complex oxides [M], layered dichalcogenides [, and nanoporous semiconductors The k p fonnulation has also enabled calculation of the complex band stmcture of the A1 (100) surface...

Ruthenium and osmium form only disulfides. These have the pyrite structure and are diamagnetic semiconductors this implies that they contain M . RuSc2, RuTc2, OsSc2 and OsTc2 are very similar. All 6 dichalcogenides are obtained directly from the elements. [Pg.1081]

Layered dichalcogenides, such as sulfides or selenides of Ti, Mo, W, Zr, Ta, Nb, V, and Cr, are able to dissolve certain alkali metal ions and in some cases posttransition (pseudo-alkali) metal ions (Cu, Ag ), via a mechanism in which the guest is inserted between the dichalcogenide layers. Lithium ion intercalation into TiS2, which among layered dichalcogenides has been one of the most prominent cathode... [Pg.322]
