Surface Plasmons

Around slide 3, I called the statistics governing the model of conduction Bose-Einstein statistics. Of course they are Fermi-Dirac statistics. I think it was sleep deprivation, sorry about that.

I understand! I understand! Thanks for a wonderful explanation, with the conceptual material so well presented before even a breath of mathematics. You are a wonderful teacher!

[Sierra]

I graduated awhile ago and still come back to your lecture. Keeps my brain fresh

[Scott-ifce]

Im in my third year Nanoscience undergrad....and this is the best explanation I've found explaining surface plasmons compared to any research paper or notes I've read.

[sareekajoshi]

This has been such a lifesaver! Thanks for such an intuitive and lucid video!!

[emilyf]

Thank you from a freshman chemistry student struggling through a lab on this!!

[Zay_aart]

I really confused about this topic on my thesis and you really good to explained about it. Thank you. You have helped many people. ☺

[marcomikkers]

You are wonderful, I study Tax Law and yet I understood this fully (except from the math). You are a very talented communicator and science educator :)

[Salarzani]

You explained so many questions to me, that I had since I started my chemistry studies, with this video. Thank you for your precise explonations!

Bose-Einstein statistic cannot be applied on electrons, since they are fermions. I guess it was just a momentary black out. Otherwise, very nice explanation.

Thanks Tonya for your valuable lecture, we scientists often miss the -read between the lines- information in technical books and your information regarding the physical picture at what happens inside the bulk and surface are really nice. The phase difference between incoming and radiated plasmon light can be understood due from the dispersion relation of the classically damped harmonic oscillator phase lag for high frequency (e.g. visibe light) and your explanation regarding quantum confinement of nanoparticles can also be understood from the particle in a box model I am sure you already know all this stuff and its always nice to see things from a physical picture framework as you explained.

The Figure with the two spheres is super confusing.
It almost looks like the distance between the NPs must be 1/2 wavelength. But thats not the case. The distance between the NPs are topic of plasmonic surface lattice resonances.

This Is a great video the microphone hurts my ear slightly so i keep volume halfway all in all this is an absolutely awesome explanation I just started to learn about Plasmons and this is the tip of the iceberg Fermions really make more sense of it all now. Thank you for this lecture I have subscribed now.

[hasanasim]

So helpful! This is the simplest definition of surface plasmons I have found on the web.

[RajendraKumar-qqxz]

Superb lecture..clearly explained the surface plasmons. Thanks a lot.

[tejobhiru]

wow..! what a crsytal clear explanantion of a a concept so difficult to visualize..! thank you so much... respect and gratitude..!

[srividhyag.b.]

One line. You're the best, professor.

7:15 are those waves in the metal phonons?

[prajnan]

Why we call it as UV-Visible absorption spectra instead of extinction spectra? Why we tell absorption peak of nanoparticles instead of extinction peak..?

[azeredo_marina]

Great explanation! For the first time I understand surface plasmons and how they are formed :))

I'm so glad I found your channel. If you have anything on surface enhancement Raman and IR, I'll buy tickets to the first row, please
