Solid State Physics in a Nutshell: Week 4.1 - Ewald sphere

[@sakuragrl08]

Oh my gosh, thank you for making this video.

[@homayounhashimi2125]

that was really great, thanks for making

[@tutornick.iphysics]

Thank you! your explanation is very easy to understand!

[@Silimun]

Thank you very much. This helped me a lot.

is the magnitude of the k and k prime vector relevant?

[@erictoberer4874]

Within the context of the Ewald sphere approach, the magnitude of the vectors sets the size of the sphere. The bigger the sphere, the more likely you'll strike a reciprocal lattice point. As a case example, TEM uses high energy electrons which have huge k and k' vectors. When you do TEM diffraction, it's incredibly easy to find diffraction reflections.

Eric Toberer and to increase the magnitude you would just move the sensor or detector further away from the sample?

[@gillesbaumann675]

Awesome thanks!

[@renatn8484]

perfect!

sooooo awesome, material science & engineering is basically a physics degree hahah you guys did a great job! p.s. love the gender diversity
