1. The problem statement, all variables and given/known data
this is a lab task, i have found out the IV characteristic of the diode, now they ask me to suggest a procedure to find the constant A, in the equation I= AT^3 x exp (E/ kT), T being the temperature, and I = saturation current 2. Relevant equations i know how to find ideality factor fron the the IV graph, but can I find 'A' from the IV graph ? If not, then what other test equipment and procedures do i need to find 'A' ? Is 'A' related to the intrinsic carrier concentration in any way? 3. The attempt at a solution its very urgent, so i ll really appreciate a prompt reply. thanks :) 1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution
