Comment on the Initial-Rise Method for Determining Trap Depths

Abstract

For the determination of the trap depth from thermoluminescence and thermally stimuated current‐glow curves commonly the initial‐rise method by Garlick and Gibson is used. This method provides accurate results only if the condition Rh(T₀)[2/z−1] ≤f(T₀) is fulfilled. R is the retrapping factor, z the filling ratio of the traps at the temperature T₀, f the concentration of unoccupied recombination centers, and h the density of trapped electrons.
