What does "valence band mixing" means?
Could you provide me some reference about it?

Valence band mixing refers to the phenomenon in which the energy levels of electrons in the valence band (outermost shell) of an atom or molecule are altered due to interactions with nearby atoms or molecules. This mixing can result in changes to the electronic properties of the material.
Valence band mixing occurs when the wavefunctions of electrons in the valence band overlap with those of electrons in neighboring atoms or molecules. This can happen through various mechanisms, such as through chemical bonding or through the influence of an external electric field.
The consequences of valence band mixing can include changes to the electronic and optical properties of a material. For example, it can affect the energy levels of electrons, the conductivity of the material, and the absorption and emission of light.
Valence band mixing is important in materials science because it can significantly impact the properties and behavior of materials. Understanding and controlling this phenomenon is crucial for the development of new materials with desired properties for various applications, such as in electronics and photonics.
Some references for further reading on valence band mixing include scientific articles and textbooks on the topics of materials science, solid state physics, and quantum mechanics. Some specific sources include "Introduction to Solid State Physics" by Charles Kittel and "Principles of Electronic Materials and Devices" by Safa Kasap.
