What Causes Reflection and Transparency in Solid State Physics?

In summary, the conversation discusses common questions about the microscopic details of reflection and transparency in solids, and how these processes are often misunderstood as being caused by atomic transition. The conversation also mentions a resource, "Optical Properties of Solids" by Mildred Dresselhaus, which delves into the complexities of absorption and reflection involving a large number of particles and atoms rather than individual ones.

We have very frequent questions regarding the "microscopic" details of the process of reflection, the cause of transparency, etc. in solids. In many cases, people often still think of this as being caused by "atomic transition", neglecting the fact that these are solid state physics and not occurring on individual, isolated atoms.

This is a http://www.eknigu.org/get/P_Physics...ties Of Solids (lecture notes)(198s)_PS_.pdf", written by one of the giants in the field of material science/condensed matter physics - Mildred Dresselhaus.

As one can see, the process of absorption and reflection isn't trivial, but it always involves a LARGE conglomerate of particle and atoms, making it NOT an isolated, single-atom process.

Nice link. Thaks Zz.
 

1. What are the different types of optical properties of solids?

The different types of optical properties of solids include absorption, reflection, transmission, refraction, and dispersion.

2. How do the optical properties of solids differ from those of liquids and gases?

The optical properties of solids differ from those of liquids and gases because their molecules are arranged in a more orderly and rigid structure, leading to different interactions with light.

3. What factors can affect the optical properties of solids?

The optical properties of solids can be affected by factors such as the material's composition, crystal structure, and surface properties, as well as external factors like temperature and pressure.

4. How are optical properties of solids measured?

The optical properties of solids can be measured using techniques such as spectrophotometry, ellipsometry, and reflectometry, which involve shining light on the material and analyzing the reflected or transmitted light.

5. What are some practical applications of the study of optical properties of solids?

The study of optical properties of solids has many practical applications, including the development of new materials for use in optics and electronics, as well as in fields such as solar energy, medical imaging, and telecommunications.
