Design, fabrication and characterization of double-gated vertically aligned carbon nanofiber field emitter arrays

In this work, we designed and fabricated two types of double-gated isolated vertically aligned carbon nanofiber field emission arrays (VACNF FEAs) to study how the tip position relative to the gate affects the device performance. In the first type, the tip is in-plane with the gate, and in the second type, the tip is 0.9 mum below the gate. To quantify the… CONTINUE READING
