Abstract
The poor crystallinity of copper-phthalocyanine (CuPc) thin films fabricated via KrF laser ablation is significantly improved by three different assisting methods applied during deposition: (1) elevating substrate temperature only up to 50°C; (2) irradiating with HeNe laser of ∼ 200 μW/cm 2 ; (3) applying DC electric field. Highest crystallinity is obtained when the film is deposited under DC electric field of ∼ 50 V/cm in the direction of film thickness. This in-process electric poling also works for 4-dialkylamino-4′-nitrostilbensen (DANS) film.
