NettetSECCM and SICM can be used for controlled delivery and to pattern and fabricate structures at interfaces. A key thesis of our work is that complex electrode surfaces can be broken down and studied as set of simpler “single entities” (e.g., individual steps, terraces, defects, crystal facets, grain boundaries, single particles). durham jcr john snow https://micavitadevinos.com
