Probe size
[edit]Thanks for a good article!
Wondering about the probe size of 50 nm given in 'Advantages'. Why this large number? Even old hardware without a corrector or field emitter can get a STEM probe down to a couple of nm (compared to <0.1 nm with both). Does the probe move around slightly during precessing due to imperfect alignment, thus effectively hitting a larger area? -Yikkayaya (talk) 13:02, 23 January 2017 (UTC)
- Ah, I found the ref that gives the explanation :) [1] -Yikkayaya (talk) 13:13, 23 January 2017 (UTC)
