• Effective conductivity
• Electrical conductivity
• Metal contacts
• Non equilibrium
• Nonequilibrium temperatures
• recombination

In a recent publication [J. Electron. Mater., 46, 585 (2017)], a number of formulae are presented for the effective conductivity of a bipolar semiconductor sandwiched between two metal contacts. However, the results are shown to be nonphysical, and the explanation is traced to errors appearing in previous literature on the subject.
