Field Emission: High Performance Field Emitters (Adv. Sci. 5/2016)

Field Emission from Lateral Multiwalled Carbon Nanotube Yarn Emitters

A field emission from a lateral emitter made by a multiwalled carbon nanotube (MWCNT) yarn was investigated. The lateral emitter showed an excellent field emission performance with a low turn-on electric field of 1.13 V/μm at an emission current of 1 μA, high emission current of 0.2 mA at an applied voltage of 700 V, and longtime emission stability for over 20 h without any significant current ...

Enhanced Field Emission from Diamond Coated Molybdenum Emitters

The field emission characteristics of individual Mo emitters were measured before and after diamond deposition, as well as before and after annealing. After coating without annealing, the emission current increased dramatically. Subsequent annealing resulted in further increases in emission and improved current stability. After coating, the energy distribution of the emitted electrons was found...

High Performance Field Emitters

The field electron emission performance of bulk, 1D, and 2D nanomaterials is here empirically compared in the largest metal-analysis of its type. No clear trends are noted between the turn-on electric field and maximum current density as a function of emitter work function, while a more pronounced correlation with the emitters dimensionality is noted. The turn-on field is found to be twice as l...
