“…The LizTiS2 system exists as a continuous nonstoichiometric phase for 0 ~ x ~ 1 and has a high free energy of formation (3). Several other layered and chain structure compounds have also been investigated, including the trichalcogenides (4,5), KFeS2 (6, 7), NbSe4 (8), MPS8 (M = Ni, Fe) (9,10), and MoO8 (11)(12)(13)(14).
