kristallmomentumvärden
Kristallmomentumvärden, often referred to as crystal momentum or Bloch momentum, are fundamental concepts in solid-state physics. They describe the momentum of an electron within a crystal lattice. Unlike the free momentum of an electron in vacuum, crystal momentum is not a conserved quantity in the classical sense because of the periodic potential of the crystal lattice. Instead, it is a quantity that characterizes the electron's state and its wave-like behavior within the crystal.
The crystal momentum is quantized and is closely related to the electron's wave vector, denoted by k.
The concept of crystal momentum is crucial for understanding various solid-state phenomena, including electrical conductivity, optical
