Time-resolved photoluminescence of undoped InP
Abstract
Energy and time-resolved photoluminescence data have been obtained for nominally undoped (n 4.5×1015 cm−3) bulk InP grown by the vertical-gradient freeze method. The data were taken as a function of temperature, from 80 to 290 K, and analyzed using a solution to the continuity equation. The resulting lifetime values range from 300 ns to 3.2 μs, and surface recombination velocities were fund to be on the order of 103 cm/s. The temperature dependence can be explained by assuming a radiatively limited recombination with a resulting B coefficient ≥5.9×10−11 cm3/s at 300 K.
