Standing nanowires arrays

The effectiveness and high fidelity of electrochemical replication possible using this method is demonstrated in Fig. 2.12. In this case a PFS-h-PLA template was aligned at 180°C for 35 h with an applied field of 130 V pm and the PLA component

In this section advanced developments of the PLD technique are shortly described, e.g., the combinatorial approach and laser MBE. Because of the increasing research interest in ZnO-based nanostructures, the established PLD (at background gas pressure 10-4—3 mbar) was extended to much higher pressures of 50-200 mbar to grow arrays of free-standing ZnO nanowires. This unique high-pressure PLD process allows the growth of ZnO-based nanostructures with controlled shape and diameter and excellent optical properties.
