Research Abstract

oriented single crystal magnetite whiskers 30 to 200nm in diameter were synthesized on a stainless steel plate by means of the combustion flame thermal oxidation process. The whiskers were applied to spin-polarized electron field emitters at room temperature. The growth technology developed in this project was also applied to the synthesis of spinnable carbon nanotubes.
