  • Abstract
    Detailed measurements have been made of the base and collector-current characteristics of both n-p-n and p-n-p silicon transistors as a function of temperature. The collector current shows ideal behavior over the temperature range -60 to 150°C in that I_{C} \\infty \\exp (eV_{BE}/kT) . On the other hand, the base current is nonideal: I_{B} \\infty \\exp (eV_{BE}/nkT) , where n > 1.0 . The nonideality of IBis the main source of the temperature dependence of h_{FE} = I_{C}/I_{B} . There is no evidence for bandgap narrowing in the devices we have investigated. The temperature dependence of the collector current is given by I_{C} \\infty T_{m} \\exp (-e E_{g0}/kT) \\exp (eV_{BE}/kT) , where m = 1.4 or 1.7 for n-p-n or p-n-p devices, respectively. E_{g0} = 1.19 \\pm 0.01 eV. This result is consistent with the findings of others. The base current is a complicated function of temperature due to the presence of nonideal components.
