Interpretation of the Selected Area Diffraction Pattern
Which type of electron interaction is primarily responsible for the contrast seen in HRTEM images?
In HAADF-TEM, what does an increase in the atomic number (Z) of the elements in the sample typically result in?
Which of the following is a major advantage of HRTEM over Scanning Electron Microscopy (SEM)?
Systematic absences in a diffraction pattern can help determine:
What happens to the SADP when a sample contains high-density dislocations?
A diffraction pattern contains spots indexed as (220) and (002). Which zone axis satisfies both reflections?
Which diffraction feature is most indicative of stacking faults?
For a cubic crystal, two diffraction spots are measured with d-spacings of:
d1 = 2.03Å
d2 = 1.43Å
The ratio d1/d2 = 1.42. Which pair of planes is most likely represented?
d1 = 2.03Å
d2 = 1.43Å
The ratio d1/d2 = 1.42. Which pair of planes is most likely represented?
