FIG. 1.

Dependence of the gSP reduction on photoexposure time. Residual SP for a sufficiently long exposure time was estimated to be 0.18 V. A thick solid curve is obtained by Eq. (1), whereas a thin solid curve is a representative single exponential curve with time constant 40 s. The inset shows PL spectra obtained during the gSP reduction.

FIG. 2.

Dependence of the gSP reduction on photoexposure intensity with a fixed photoexposure time of 5.0 s. Residual SP in this measurement was estimated to be 0.44 V. The thick solid line (P-F) is derived from Eq. (1) with and . For comparison, a representative single exponential curve (exp, dotted curve) with a constant and a fitting curve with dipole-alignment randomization mechanism (Sugi, thin solid curve) are given for comparison. The inset gives the same dependences with -scale magnification.

Preservation of gSP pattern in the dark. Three samples with the same gSP pattern (a line and space followed by and line/space prepared by contact-mask photoexposure) were stored in the dark at room temperature, at (reduced pressure), and at (reduced pressure), respectively. KFM potential plateau in the gSP pattern on each sample was measured after preservation. The KFM pattern observed after 1 month reservation at room temperature and that after 1 year at are given as insets .

Abstract

The characteristics and mechanisms of photoinduced reduction in giant surface potential (gSP) on tris(8-hydroxyquinolinato) aluminum(III) thin films were investigated and discussed from the results of the reduction dependences on exposure time/intensity and the preservation of photopatterned gSP. The reduction dependences are explained well with numerical-model calculation of surface potential reduction due to the drift of photoexcited carriers assuming the Poole–Frenkel formula for electron mobility. The preservation of patterned gSPs suggests the existence of deep traps involved in the carrier-drift mechanism.
