| 中文摘要 | the self-assembled growth of vertically well-aligned zno nanorod arrays with uniform length and diameter on si substrate has been demonstrated via thermal evaporation and vapor-phase transport. the structural, photoluminescence (pl), and field emission properties of the as-prepared nanorod arrays were investigated. the pl spectrum at 10 k shows a strong and sharp near-band gap emission (nbe) peak ( full width at half-maximum (fwhm) = 4.7 mev) and a weak neglectable deep-level emission (dl) peak (i-nbe/i-dl= 220), which implies its good crystallinity and high optical quality. the room-temperature nbe peak was deduced to the composition of free exciton and its first-order replicas emissions by temperature-dependent pl spectra. the field emission measurements indicate that, with a vacuum gap of 400 am, the turn-on field and threshold field is as low as 2.3 and 4.2 v/mu m. the field enhancement factor beta and vacuum gap d follows a universal equation. |
