Excellent site! I found the same one last week but haven't had a chance to dive in. In the meantime, I'm also posting here a great IIT video about Oscillators with a brief focus on the electrical circuit diagram in question: It's great to see that the parallel capacitance modeled solely...

FYI for anyone interested in this subject matter, I found a great YouTube video which explains visually the dipole moment that is created in a piezoelectric material: I wish he shared his references, but this is what I was curious to learn more about. It seems polar bonds make the dielectric...

Lol I do 😅 Elastic collisions were very critical in the development of crystallography diffraction experiments last century (Bragg, Laue, Debye, Rutherford, Davisson, etc.) and I'm trying to develop a deeper mathematical understanding of their scattering patterns which do not rely on...

I see. And the author is in agreement with you - that it is a mechanically resonant - dominant behavior. From p220 of the previous attachment: So the elastic collisions from the current cause mechanically stored potential energy (hence the resonance) which can operate as a frequency-selective...

That's great insight on oscillation mechanics, thanks. I found another resource this time titled "the piezoelectric quartz resonator" p216 (attached): This description of the reverse current effects of the piezoelectric stress-and-strain (to produce AC) is what I was curious to learn...

Oh that’s interesting, the oscillation is an acoustic effect and not electrical? I would expect the (inverse) piezoelectricity to require polarization of the material on the atomic level to, say, cause a phase shift in a DC input to make an AC waveform.

Thank you for the resource! I guess my question is if the physical nature of the quartz resonance has ever been treated as a linear harmonic oscillator according to the dipole moments in the crystal in the presence of an electric field disturbance? The ad hoc equivalence circuit approximation...

Hi! As I outlined in my https://www.physicsforums.com/threads/hello-reality-anyone-familiar-with-the-davisson-germer-experiment.985063/post-6305937, I'm curious to ask if there is anyone with knowledge on the theory of the piezoelectric effect on this forum? I think it's fascinating how a...

Great thanks!

Thank you for the welcoming and insight! I am aiming to at least gain a better understanding of the Lorentz Harmonic Oscillator's application to crystal oscillation - hopefully this isn't prohibited. :smile:

Lol I try to make an entrance :-p and thanks!

Greetings, I'm happy to find such an enthusiastic community with an encyclopedic knowledge and mathematical rigor. I'm a Biomedical Engineering Researcher that's had to breach into the world of condensed matter physics to better understand the physical principles of the piezoelectric crystal...
