When doing any type of high-resolution imaging of a large single crystal specimen, you will always get the most detail in your images by aligning the sample along a major crystallographic zone axis; but what is a zone axis and how do we align to it when performing S/TEM? Thanks for watching! Please like, subscribe, and share and let me know if you have any questions or comments. Video topic requests are always welcome and appreciated; I enjoy making these videos and wish I could make them more frequently, but the demands of my job make it tough to do so; I’m in charge of 3 S/TEMs, 2 dual beam FIB/SEM systems, and 1 SEM and this keeps me very busy!
