Recessed Carbon Nanotube Article and Method for Making Same

NIST Inventors

Chris Yung , Nathan A Tomlin and Dan Schmidt

patent description The proposed invention is a microbolometer array utilizing vertically aligned carbon nanotubes (V ACNTs) as broadband absorbing elements inside wells micromachined into a substrate. Membranes at the base of each well support the VACNTs and act as a weak thermal link. The VACNTs
