STRUCTURE AND SUPERCONDUCTIVITY IN LITHIUM-INTERCALATED NIOBIUM DICHALCOGENIDES

Abstract:

The series LixNbS2 (0 ≤ x ≤ 0.50) and LixNbSe2 (0 ≤ x ≤ 0.67) have been prepared by high-temperature reaction of Li2S, Nb, and S or Li2Se, Nb, and Se. Structures have been determined by analysis of X-ray powder patterns with polytypism observed in the sulfide series. Evidence of staging and Li ordering is reported, and crystal parameters are proposed for a second-staged sample, Li0.2NbSe2. In the series LixNbSe2, Tc exhibits a monotonic decrease with increasing lithium content, falling to les...
