| abstract |
In the present invention, a composition of carbon nanotubes (CNT) is produced in the ink, which can be dispensed via an inkjet coating process. This CNT ink is distributed to the wells formed in the cathode structure. Certain embodiments of the present invention provide a process for uniformly coating CNTs in a well structure, as shown in FIG. 1 (a). The well structure may have four or more walls (or one wall in the case of round holes) to form a hole. |
