Problem
1. A periodic lattice of W and C is used as a λ/4 X-ray mirror. What are the layer thicknesses that should be used for 100 eV X-rays?
2. Oxygen is soluble into titanium up to 34 atomic%. What will be the thickness of a silicon dioxide film that can be dissolved by a 50 nm-thick titanium film? Titanium density is 4.5 g/cm3, silicon dioxide density is 2.3 g/cm3.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
