Effective lifetimes as a function of excess carrier density for the light boron diffusions. The solid lines are fits to determine the bulk lifetime and emitter components.
Emitter saturation currents for the boron diffused samples as a function of Fe dose.
Emitter saturation currents for the phosphorus diffused samples as a function of Fe dose.
Relative spectral photoconductance of the control sample and the highest Fe dose sample with heavy boron diffusions.
