A critique of the theory of p-n-p-n devices
James F. Gibbons · IEEE Transactions on Electron Devices · 1964
A review of various papers dealing with p-n-p-n device characteristics shows essentially different interpretations of 1) the condition for switching and 2) the operating state defined by\alpha_{p}+ \alpha_{N} = 1. The present paper attempts to show the relationship between these various papers and to clarify the conditions which exist at the switching point and holding point.
