This sort of "concentration varies with $\exp(-E/k_BT)$" equation also pops up often in chemistry and electronics (Goldmann equation, Nernst equation, diode current-voltage-characteristics,...) | This sort of "concentration varies with $\exp(-E/k_BT)$" equation also pops up often in chemistry and electronics (Goldmann equation, Nernst equation, diode current-voltage-characteristics,...) | ||
