Abstract :
ZnO/CNTs composites were used to fabricate the field emission layer onto electrode by screen printing process. Through adding a graphene resistive layer between the electrode and the emission layer, the turn-on field was decreased from 1.6 v/μm to 1.0 v/μm; the emission uniformity and the emission stability were improved apparently.
