Description

Application

Cyclopentadienyl compounds of Barium are very commonly used ALD/CVD precursors for depositing Barium containing thin films; example BaTiO3; BaZrO3
films. Cyclopentadienyl groups form weaker bonds with Barium, but have stronger bonds within the ligand thus preventing carbon contamination of the
films. Cyclopentadienyl precursors of barium sublime under reduced pressures, with tetrahydrofuran adducts showing volatility also under atmospheric
pressure. The tetrahydrofuran adducts loose the coordinated THF when evaporated. Complexes with bulky cyclopentadienyl ligands are more thermally
stable and volatile.
Barium containing thin films finds applications as host lattices for luminescent materials, high temperature superconductors, high permittivity
dielectrics and ferroelectrics.
