Abstract

Patterned porous silicon (PS) films were fabricated based on hydrogen ion implantation technique and typical electrochemical anodic etching method. The surface morphology and characteristics of the films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and atomic force microscopy (AFM). The efficient field emission with low turn-on field of about 3.5V/μm at current density of 0.1μA/cm² was obtained. The emission current density from the PS films reached 1mA/cm² under a applied field of about 12.5V/μm. The experimental results demonstrate that the PS films have great potential applications for flat panel displays.
