In contrast to the widely accepted scenario of Mott localization as the driving force behind the gap formation in the CDW phase of layered transition-metal dichalcogenides, our results not only highlight the cr

The thermogravimetric analysis, revealing two to four distinct steps for the phases derived from TiS2 and 2H NbS2, and only one to two smeared-out steps for those derived from 1T TaS2, proves the coexistence of strongly and weakly bound intercalate molecules. The first ones cannot be ...
Our findings indicate that the nonlocal correlations, which are typically significant in systems comprising transition metal cluster units, contribute to the insulating ground state of 1TNbS2 in two distinct aspects. Firstly, they further stabilize the 13脳13 CDW among several competing structure ...
The stability of intercalated phases AgxTiS2, AgxNbS2 and AgxTaS2 is discussed on bases of EMF measurements; a comparison is made with the corresponding alkali-metal intercalates. Structures of the intercalated phases (dilute stage-1, second-stage and first stage) are compared in relation ...
