Abstract
The porous nature of high surface area and large aspect ratio nanorods arrays make them strong candidates for a range of applications from catalyst supports to energy scavenging devices. The glancing angle deposition (GLAD) technique is a straightforward and flexible method for ensuring control of morphol. and porosity in nanorod arrays. Quantifying the porous nature of nanostructured columnar arrays, fabricated using the GLAD technique, is crit. for understanding and optimizing the performance of devices fabricated using this method. The mesoporosity and pore vol. of these GLAD nanorod arrays have thus been characterized using gas adsorption (krypton adsorption at 87.3 K) and SEM image anal. techniques. To characterize the obliquely deposited amorphous titanium dioxide (TiO2) and silicon dioxide (SiO2) samples, top-down SEM images of the films were also analyzed which allowed one to det. the mean distance between columns. SEM image anal. permitted for estn. of inter-column porosity of films deposited at angles from 65° to 85°, while krypton anal. allowed for the identification of mesoporosity in films from 45° to 85°. The results provide a comprehensive characterization of GLAD film porosity which will be vital for the design of devices for a diverse set of applications from photonics to sensing to microfluidics.
