Unveiling the emergence of functional materials with STM: metal phthalocyanine on surface architectures

Author affiliations

Abstract

Metal phthalocyanine molecules with their inherent versatility call for an exploration of their fundamental properties when anchored on conducting substrates for designing new applications. In this article we present low temperature scanning tunneling microscopy (LT-STM) and spectroscopy (STS) measurements of copper phthalocyanine (CuPc) on noble metal Au(111), semimetal Bi(111), Dirac material graphene, and topological insulator surface Bi2Se3. We discuss in detail how the self-assembly of CuPc varies due to the nature of the substrate. STS measurements enable us to better understand the local electronic properties of the molecule–substrate interface. This insight provides key guidelines for using CuPc towards interface engineering for applications and for unraveling new phenomena therein.
