Electron emission from nickel-alloy surfaces in cesium vapor

Effect of substrate heating and microwave attenuation on the catalyst free growth and field emission of carbon nanotubes

“…To keep contact resistance minimum it is generally preferred that substrate has the comparable work function value with CNTs [45]. In our case, for sample A we used as-received Inconel as substrate which has work function value $4.8 eV [46] close to that of CNTs (4.7 eV). So, high contact resistance problem should not appear in this case.…”
