Kronig-Penney Model
Kronig-Penney Model
The Kronig-Penney model is a simplified model used in solid state physics to understand the behavior of electrons in a periodic potential.
ρ in the Kronig-Penney model
ρ in the Kronig-Penney model
In the Kronig-Penney model, 'ρ' represents the strength of the potential barrier.
ρ > 0
ρ > 0
The condition 'ρ > 0' indicates that the potential barriers are positive.
ρ < 0
ρ < 0
