Transmission and scanning electron microscopy are used to compare the growth of nanorod arrays in ZnO and Al-doped ZnO (2%Al) films grown by pulsed laser deposition. For a laser pulse energy of 10 mJ/pulse, nanorod arrays were formed at temperatures

This work highlights a potential pitfall associated with using optical emission to estimate the expansion velocity of material in laser ablation plumes, speci.cally when the monitored emission involves transition to a state that is present in high nu

Arrays of well-aligned ZnO nanorods have been grown on Si substrates at 600 ∘C using a catalyst-free pulsed laser deposition (PLD) method, with and without pre-deposition of a thin ZnO layer at a lower substrate temperature. Deposited products were

Arrays of well-aligned ZnO nanorods were synthesized on a Si substrate at 600 °C by 193 nm pulsed laser ablation of a ZnO target in low pressures of oxygen. Electron microscopy and X-ray diffraction revealed highly c -axis aligned, ultra-thin, needl

The recent finding that radio frequency plasma activation of CH4/PH3 gas mixtures [7] could lead to films with P:C ratios ≤3 (which also contain ∼10% hydrogen, distributed evenly throughout the bulk) has served to trigger further research into ne
