Field emission properties of DLC and phosphorus-doped DLC films prepared by electrochemical deposition process

Improvement of field-emission-lamp characteristics using nitrogen-doped carbon nanocoils

“…The sp 2 clusters can also cause electron delocalization and facilitate electron hopping between the clusters. In addition, the clusters were likely to overlap, which also further accelerated electron transport between the connecting clusters [55,57]. These sp 2 clusters with good connectivity acted as a conductive channel in Fig.…”

“…Previous studies indicate that incorporating suitable amount of nitrogen into carbon films will form CN x , which can enhance their field emission properties [45][46][47][53][54][55][56][57][58][59]. It may be attributed to the weak donor activity of nitrogen, which raises the Fermi level, lowers the work function, and the formation of more sp 2 clusters in carbon films [53].…”

Doped Amorphous Carbon Films Prepared by Liquid Phase Electrodeposition

“…Phosphorus combined with carbon in the form C=P bond and the graphitization degree of the films enhanced confirmed by XPS and Raman spectroscopy. The experiments of the field emission characteristics showed that the threshold electric field and current density for the undoped-and doped-P films were 12 V/mm, 45.7 μA/mm 2 , and 9.5 V/mm, 12.6 μA/mm 2 , respectively [42]. Similarly, the emission properties can be also improved by doping sulfur using carbon disulfide [43] or thiophene [44] as dopant.…”

Properties of W incorporated diamond-like carbon films prepared by pulsed-laser deposition

“…[1][2][3][4]. The large change in the properties of the DLC films principally results from the different bonding configurations.…”
