Atomic-scale Imaging of Orgnanic/Inorganic Heterostructures: from Single Molecules to Devices

Controlling nano-scale organic-inorganic interfaces is integral to properties and performance from biomaterials to emerging organic electronics. Quantitative imaging at atomic length scales is, however, highly challenging on account of the chemical complexity and hybrid nature of such interfaces. We have pioneered atom probe tomography (APT) for the imaging of biomineral nano-composites.1 Herein, we propose to leverage our experience in sample preparation, APT operation, and spectral interpretation to establish the scope of APT for the characterization of interfaces in emergent organic/inorganic hybrid materials from single nanoparticles to devices.
