TīmeklisAn equation that is highlighted with a box, such as Eq. (1.7), is particularly important and often cited. Equation (1.7) is the Fermi function, or the Fermi–Dirac distribution function, or the Fermi–Dirac statistics. EF is called the Fermi energy or the Fermi level. f(E) is the probability of a state at energy E being occupied by an electron. Tīmeklis2015. gada 26. aug. · 3. What exactly is the relation between these 3 quantities? As far as I can tell the work function is the energy needed to bring an electron from the fermi level out into vacuum, while affinity is from the bottom of the conduction band. Does this then mean that they can be used to calculate the band gap between the conduction …
