WebLes porteurs tendent à se recombiner pour retourner à leur valeur d’équilibre. Nous avons: pnnp=pn0nn0exp (qV/kBT)=ni2exp (qV/kBT) (pn=pn0exp (qV/kT) La probabilité de recombinaison atteint une valeur maximum quand nn=pn=niexp (qV/2kBT). Webband. We will see later that this probability is ~exp(-Eg/2kBT). At room temperature, kBT = 0.025eV. This factor is exp(-80) ~ 10-35 when E g = 4eV; but it lowers to exp(-5) ~ 10-2 when E g = 0.25eV. In the latter, conductivity is observable. Semiconductors are insulators at T=0, but has an Eg is as such that at temperatures below the
