Abstract

Carbon nanotubes (CNTs) have been of interest to researchers because of their superior electrical, thermal and photonic properties. Applications of the energy saving devices and optical devices are expected. In the field of optical device applications, for example CNT has the applicability to an photonic metamataterial[1], field emitter elements[2] and solar cells[3]. However, it is known that optical properties depend on the density and structure of CNT forest[4]. Therefore, the precise control of structure and optical properties is essential to utilize the CNT forest for optical applications. The frost column-like CNT forest, a carbon film supported by low-density CNT forest, is expected as a floating mirror or a floating thin film on substrate. In this report, the optical properties of frost column-like CNT forest were investigated.
