Are there any advantages to carrier lifetime measurement using reverse recovery method compared to OCVD method?
Could you make your question more clear and specific.
I have seen in some papers and theses (link 1 is an example) that a constant generation rate is assumed for solving drift-diffusion equations. My questions are, why this assumption is valid?Is...
