Measurements and analysis of advanced field emission cold cathodes

This paper reports on measurements and analyses of field emission from both copper and aluminium cathodes. To analyze the data, a numerical model of electron emission was developed using a transfer matrix function method. The work function and effective field enhancement factor of the cathodes were...

Zusammenfassung:This paper reports on measurements and analyses of field emission from both copper and aluminium cathodes. To analyze the data, a numerical model of electron emission was developed using a transfer matrix function method. The work function and effective field enhancement factor of the cathodes were obtained.
