摘要：

The charge-carrier traps in the neat carbazole crystal have been found and were interpreted as dipole traps formed by the intrinsic orientational crystalline defects appearing when a molecule is rotated by 180 degrees along the long in-plane axis as compared to the bulk molecules. The depths of trapping states established on the neighboring molecules of crystal in the vicinity of one, two and tree reoriented molecules was calculated. Energetic spectrum of dipole traps was studied by fractional thermoluminescence and the experimental results are in good agreement with calculation.
