“…Other experiments have already indicated that the emission from CuPc arises from multiple states 26,27 and that the different image types can be associated with different Fowler-Nordheim slopes. 28 In the course of our experiments, a single tantalizing run of data was acquired in which a FEEM quadruplet with a doublet barrier map spontaneously converted to a FEEM doublet with the same orientation as the barrier map doublet as the field strength was increased. Unfortunately, insufficient data were acquired to construct a barrier map for this subsequent FEEM doublet and the effect has proven difficult to reproduce.…”

The field-emission tunneling barrier has been mapped for the doublet and quadruplet emission patterns associated with organic adsorbates on tungsten. The tunneling barrier was mapped by photometric probe-hole field-emission electron microscopy (PhotoFEEM). The adsorbates were deposited by evaporating a film of the molecule copper-phthalocyanine (CuPc) but it may be polymeric groups of CuPc or decomposition products. The tunneling barrier displays unexpected structures that are not seen in the corresponding field-emission images. Doublet patterns observed in the FEEM image can display singlet structures in the corresponding PhotoFEEM barrier maps. Similarly, quadruplet patterns in the FEEM image can display doublet structures in the PhotoFEEM barrier maps. This behavior is similar to supply limited tunneling previously observed in the field-emission barrier of a clean tungsten emitter. An analysis of deviations from purely linear Fowler–Nordheim behavior indicates that the observed structures arise from independent emitters that are spatially superimposed on the surface.

“…Emitters require a low effective work function, high geometrical aspect ratio, and good thermal and chemical stability 5 6 7 . A variety of one-dimensional (1D) nanomaterials have been studied as novel emitters, including 1D carbon nanomaterials 8 9 10 11 , 1D nano-metal oxide 12 13 14 15 , and 1D nano-metal materials 12 16 17 18 . However, from a practical point of view, the in situ growth of emitters at low temperature (<450 °C) on a desired substrate or the production of emitters in powder form are required for industrial applications.…”

A field-emission light source with high luminance, excellent luminance uniformity, and tunable luminance characteristics with a novel lateral-gate structure is demonstrated. The lateral-gate triode structure comprises SiC nanowire emitters on a Ag cathode electrode and a pair of Ag gate electrodes placed laterally on both sides of the cathode. The simple and cost-effective screen printing technique is employed to pattern the lateral-gates and cathode structure on soda lime glass. The area coverage of the screen-printed cathode and gates on the glass substrate (area: 6 × 8 cm2) is in the range of 2.04% – 4.74% depending on the set of cathode-gate electrodes on the substrate. The lateral-gate structure with its small area coverage exhibits a two-dimensional luminance pattern with high brightness and good luminance uniformity. A maximum luminance of 10952 cd/cm2 and a luminance uniformity of >90% can be achieved with a gate voltage of 500 V and an anode voltage of 4000 V, with an anode current of 1.44 mA and current leakage to the gate from the cathode of about 10%.
