Since its discovery in the 1980s, scanning tunneling microscopy (STM) has been a powerful tool for exploring the nanoscale due to its capabilities for atomic-resolution imaging, tunneling spectroscopy, and atom/molecule manipulation. These unique capabilities of STM enable studies of problems related to the scaling of conventional information technologies to atomic dimensions, and provide opportunities for studying the fundamental bases of novel paradigms. For example, molecule-based devices are of interest for next-generation technologies due to the easy tunability of organic molecules with relatively simple chemical methodologies. This motivates our STM studies of organic-metal interfaces and metallo-organic complexes at the single molecule level.

Continuing technological advances require the element analysis of increasingly smaller structures in many fields of materials science, including semiconductors and nanotechnology in general. The element composition of thin electron transparent samples can be analyzed in the nm-range using transmission electron microscopes (TEM) or, specific sample holders provided, in the field emission scanning electron microscope (FE-SEM). Nevertheless both methods often require complex sample preparation. An alternative method is to analyze bulk samples with a FE-SEM.

This Transmission Electron Microscope (TEM) investigation uses the retrieved complex exit-wave function in combination with the geometric phase analysis (GPA) to analyze strain located at faceted Al-Pb hetero-interfaces. It was found that the outer regions of a Pb nanoparticle were strained (compressed) which explains, according to the Clapeyron equation, an elevated melting in terms of interface strain.
