摘要
The ramp recovery method for the measurement of carrier lifetime in p-i-n diodes is analyzed to show that Tien and Hu's formula tau = square-root t(A)(t(A) + t(B)), where t(A) and t(B) are the two intervals for the recovery, gives a good estimate of the lifetime. The recovery can be assumed to be complete at a time t2 at which the reverse current has reduced to 10% of its peak value. This eliminates the necessity of assuming the ramp recovery waveform to be a triangle.
