Latest Patents

One of his latest patents is titled "Methods to pattern carbon nanotube sheets." This patent discloses effective techniques for patterning carbon nanotube (CNT) sheets. A carbon nanotube forest is grown on a catalyst-incorporated substrate, from which CNT sheets are drawn. These sheets are then stacked on a substrate and etched using a shadow mask through a controlled etch process. In some implementations, the etching is performed in a capacitively coupled plasma (CCP) etching system, where the CNT sheets are selectively exposed to oxygen plasma via the shadow mask.

Another significant patent is the "Method of manufacturing electrodes using carbon nanotube sheets." This invention focuses on growing spin-capable multi-walled carbon nanotube (MWCNT) forests in a repeatable manner. The research highlights that the spinning capability depends on the alignment of adjacent MWCNTs, which is influenced by the high areal density of MWCNTs and the short distance between them. By starting with the appropriate Fe nanoparticle size and density, one can predict the growth of spin-capable forests reliably.
