Talk:Friedel oscillations

[Untitled]
The figure of the STEM picture (http://en.wikipedia.org/wiki/File:LDOS_image_showing_friedel_oscillation.jpg) has an illegible scale bar. The scale is important, especially considering that wavelength vs energy is the main point of the figure. Scale information should be added.

Need to clarify conclusion of Scattering Description
The conclusion of the main section of this article includes the equation $$\rho(\mathbf{r}) = \rho_0 + \delta n \frac{\cos(2 k_F|\mathbf{r}| + \delta)}{|\mathbf{r}|}$$ but little attempt to unpack the meaning is made. In particular, the meaning of $$\delta n$$ and $$\delta$$ should be clarified. Flies 1 (talk) 02:09, 2 December 2010 (UTC)

What is the origin of the name "Friedel oscillations"?
It is not clear from the text what is the origin of the name of these oscillations, who is this Friedel that they are named after? — Preceding unsigned comment added by 85.65.62.172 (talk) 07:36, 2 June 2011 (UTC)
