Could someone please explain what valley degrees of freedom are?
As a local minimum/maximum on the valence/conduction band in semiconductors.HallsofIvy said:What "valley" do you mean?
Valley degrees of freedom refer to the states of energy in a material that are associated with the movement of electrons in different energy valleys within the material's band structure.
The number of valley degrees of freedom in a material depends on its band structure and can vary from one to multiple valleys.
Valley degrees of freedom have a significant impact on the physical properties of materials, such as their electronic, optical, and transport properties.
Yes, the valley degrees of freedom in a material can be controlled through external factors such as electric and magnetic fields, strain, and temperature.
The manipulation of valley degrees of freedom can lead to improved performance of electronic devices, such as faster and more efficient operation, as well as enabling new functionalities.
