The STM-BJ technique enables precise and highly reproducible measurement of a molecule’s electronic transport properties, making it a powerful technique to explore physiochemical and electrochemical phenomena that are otherwise difficult to access. It has gained substantial popularity in the past 20 years, with experiments becoming increasingly diverse and sophisticated. Despite the wealth of literature, an accessible, practical guide to performing STM-BJ experiments and interpreting the data is largely absent. This tutorial includes a brief background into the development of STM-BJ measurements, followed by detailed explanations of instrumentation, data collection, statistical analysis, variations on standard experiments, and some troubleshooting methods. It is aimed at researchers looking to begin or improve STM-BJ studies in their laboratories, graduate students and postdoctoral researchers learning the technique, and readers seeking to critically evaluate the growing body of STM-BJ literature. https://research-explorer.ista.ac.at/download/21986/22020/2026_ACSPhysChem_York.pdf application/pdfno American Chemical Society2026 eng 2694-2445 4222194110.1021/acsphyschemau.6c00026 63408-424 York, Emma, and Latha Venkataraman. “Scanning Tunneling Microscope-Based Break-Junction Technique - A Tutorial.” <i>ACS Physical Chemistry Au</i>, vol. 6, no. 3, American Chemical Society, 2026, pp. 408–24, doi:<a href="https://doi.org/10.1021/acsphyschemau.6c00026">10.1021/acsphyschemau.6c00026</a>.
