Electron Field Emission Cathodes

Diode Type: Patterned CNT Structures

Substrate: ITO glass, silicon, metal, polymer etc.

Uniform Field Emission Property

2cm x 2cm square sample (4.4V/µm)	1cm diameter circular sample(1.7V/µm)

Field Emission Characteristics

Long-term Emission stability at high current

Xintek cathodes show excellent long term stability
