**4.3. Minority carrier emission rates**

For the observation of minority carrier emission, we have to first fill the level with minority carriers. This is accomplished through minority carrier injection by forward biasing the diode so that a current flows. After the end of the bias pulse, as the sample returns to the quiescent reverse bias, the deep level will emit minority carriers giving rise to a transient. Thus the DLTS measurement is the same as for the majority carrier emission except that the sign of the peak (transient) is now opposite.
