Abstract
A study has reported on the production and characterization of high-quality, structurally stable melanin thin films with electrical conductivities comparable to that of amorphous silicon. The film internal and surface morphologies were probed using scanning electron microscopy and atomic force microscopy, and found to be compact and smooth on the nanoscale. The solid-state absorption coefficients of these films were also measured and found to be between 107 and 106m-1 across the ultraviolet, visible, and near-infrared. The study shows that it is a crucial step toward harnessing melanin's optical and electronic properties in hitherto unrealized organic optoelectronic electrical devices. These melanin thin films also possess several highly desirable physical and biological properties that make them ideal for organic bioelectronic devices.
