“…PATs with 40 nm diameter pores were prepared by a twostep anodization process as described by Masuda et al [21] and used in our previous works [22,23]. The PATs are approximately 5 μm thick and have a pore density of (8-9) × 10 8 cm −2 .…”

The controllable growth of highly aligned and ordered semiconductor nanowire arrays is crucial for their potential applications in nanodevices. In the present study, both the growth orientation and the microstructure of hexagonal CdS nanowire arrays electrodeposited in a porous alumina template with 40 nm diameter pores have been controlled by simply tuning the deposition current density. An extremely low current density of 0.05 mA cm(-2) is favorable for the growth of single-crystal CdS nanowires along the normal direction of the intrinsic low-surface-energy (103) face. This can be understood well by a modified critical dimension model given in the present work.

“…PATs were prepared by a two-step anodization process as described by Masuda et al [40] and used in our previous works [41,42]. To prepare the PATs with a nanopore diameter of ∼25, 40 and 120 nm, the anodization was performed in the acid solutions 0.3 M H 2 SO 4 , 0.4 M H 2 C 2 O 4 and 0.5 M H 3 PO 4 , respectively.…”

Controlling the growth orientation of semiconductor nanowire arrays is of vital importance for their applications in the fields of nanodevices. In the present work, hexagonal CdSe nanowire arrays with various preferential growth orientations have been successfully yielded by employing the electrodeposition technique using porous alumina as templates (PATs). We demonstrate by experimental and theoretical efforts that the growth orientation of the CdSe nanowires can be effectively manipulated by varying either the nanopore diameter of the PATs or the deposited current density, which has significant effects on the optical properties of the CdSe nanowires. The present study provides an alternative approach to tuning the growth direction of electrodeposited nanowires and thus is of importance for the fabrication of nanodevices with controlled functional properties.
