Temperature dependence of the PL lifetime for the GL1 band in HVPE GaN.

The dashed line is τ2 given with Eq. (8). The solid lines are calculated using Eq. (10), with τ1 and τ2 given by Eqs (9) and (8) with τ20 = 0.67 μs and E2 = 2 meV and a = 2.8. Parameter τ1(100 K) is sample-dependent: 3.5 μs (sample RS280), 2.6 μs (B73), 0.75 μs (1007), 0.3 μs (104), and 0.17 μs (201).
