Zinc oxide nanotube arrays were prepared by hydrothermal reaction in ammonia and zinc chloride solutions, and the field emission properties were tested. The turn-on field of the field emission was extrapolated to be about 7.0 V/μm at a current density of 0.1 μA/cm2. Meanwhile, the emission current d...
