The aim is to investigate the intercalation of alkali metals into tungsten ditelluride and observe structural changes.
Intercalation of tungsten ditelluride (WTe2) with potassium, rubidium, and cesium.
Synthesis of intercalation compounds of the form A0.5WTe2.
Structural analysis of the resulting compounds.
Successful formation of intercalation compounds with distinct crystal structures.
Observation of a metal-to-semiconductor transition in the intercalated WTe2.
Abstract
We explore the cationic intercalation of tungsten ditelluride (WTe 2 ) with potassium (K), rubidium (Rb), and cesium (Cs), yielding intercalation compounds of the form A 0.5 WTe 2 ( A = K, Rb, Cs).
