✦ Synopsis

By using time-resolved optical second harmonic generation (TR-SHG) measurements, we studied carrier behaviors in poly(3hexylthiophene) (P3HT) metal-insulator-semiconductor (MIS) diodes. TR-SHG measurements probed transients of electric field distribution in the P3HT active layer. Results showed that hole injection and removal processes were non-reversal, where the response times were different from each other and the relaxation time of the transient electric field strongly depended on the hole injection process.
