Analytical electrostatic model of silicon conical field emitters. II. Extension to devices with focusing electrode

For pt. I see ibid., vol.48, no.1, p.134-43 (Jan. 2001). We extended the "bowling pin model" (BPM) presented in pt. I, to the case of double-gated conical field emitters. The model was used for trajectory calculations for both the single-gated and double-gated devices. Analysis also produced the governing relationship for the optimal operating voltages on the gate and focus electrodes of a double-gated emitter.
