The simple analysis of the junction diode shows that if the Damkohler number, \(D a=0\), no current will flow and so recombination is the main source of current flow (equation (5.136)). However, if we add a drift component as in equation (5.153), do we arrive at the same conclusion? What happens in equation (5.153) if \(D a=0\) and does it agree with the solution to equation (5.151) when \(D a=0\) ?
