Comparing this to the stan dard form we see : RDD =\u03bce Epk ,which is the drift velocity at x =0! Before comparing the thermionic emission and drift-diffusion expressions, we will look at the current through a p-n+ junction diode.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
