Intercalation of alkali metal into WTe 2 , the crystal structure of A 0.5 WTe 2 and observation of a metal-to-semiconductor transition

Key Points

• 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.
