title: Substrate dependence of Pt4 electronic properties.
abstract: We show through first-principles calculations that the electronic properties of Pt4 clusters can be tuned by adsorption on substrates with different electronic valence characters. Pt clusters exhibit a metallic character on γ-Al2O3(111) and insulator properties on CaZrO3(001). The noted difference indicates the role of the electronic valence states of the substrate atoms that directly bond with Pt.
