Surface| Summary: | We propose a procedure for synthesis of nanometer-sized thread-like zinc oxide crystals by gas epitaxis via the mechanism ”vapor-liquid-crystal” (VLC). Arrays of statistically distributed nano-whiskers on polished silicon substrates were prepared. Samples were studied by x-ray diffraction analysis and scanning electron microscopy (SEM). Nano-whiskers were found to have wurzite structure and size of d ~ 10 nm. Field electron emission was revealed at average electric fields ~105 V/cm and local current density ~10 А/см2. |
