Since the internal E-field creates a force attracting the electrons and holes, this E-field will hold the pulses of excess electrons and excess holes together. The negatively charged electrons and positively charged holes then will drift or diffuse together with a single effective mobility or diffusion coefficient. This phenomenon is called ______ .
In Haynes-Shockley experiment, ( ) can be determined from this single experiment.
In the ambipolar transport, the negatively charged electrons and positively charged holes then have the same effective mobility or diffusion coefficient. ( )
Low-level injection is that the concentration of the incorporated excess carriers is ()than the concentration of the majority carriers in thermal equilibrium.
