WebNote that from this definition it follows that in equilibrium, U = 0 holds. This quantity tells us, for example, how fast a non-equilibrium carrier density will decay, i.e. how fast full equilibrium will be reached – or, if we keep the non-equilibrium density fixed for some reason, what kind of recombination current we must expect.: This is so because U, the … Web3 Mar 2024 · Download Solution PDF. An ideal diode equation or Shockley equation is given by. I D = I S ( e q V D η k T − 1) Where I S is the reverse saturation current. q is the charge on the electron. V D is applied forward-bias voltage across the diode. η is an ideality factor = 1 for indirect semiconductors. = 2 for direct semiconductors.
