Flexible Morphology Control of Nanotube Arrays from Glancing Angle Deposition

Huang Z.F., Harris K.D., Brett M.J., University of Alberta, CA

Recently, silicon nanotubes (SiNTs) have attracted considerable attention. However, it has been challenging to grow SiNTs without any template. Another challenge is to engineer the shape of SiNTs, which to date has been limited mostly [...]

Fabrication and characterization of Alq3 electrically actuated nanospring arrays

Dice G.D., Brett M.J., University of Alberta, CA

Glancing Angle Deposition (GLAD) is a single step physical vapour deposition (PVD) technique utilizing oblique deposition angles to create porous thin film helical structures. Previous nanospring work has used inorganic materials such as SiO2. Here, [...]

Evaluation of silver nanostructures fabricated using glancing angle depostion as localized surface plasmon resonance biosensors

Gish D.A., Nsiah F., McDermott M.T., Brett M.J., University of Alberta, CA

The localized surface plasmon resonance (LSPR) biosensing capability of 175 nm thick silver nanoparticle films produced by glancing angle deposition (GLAD) was evaluated. The extinction spectra of the films exhibited a peak around a wavelength [...]

Optical and structural characterization of nanostructured Alq3 with negative in-plane birefringence

Szeto B., Gospodyn J., Hrudey P.C.P., Sit J.C., Brett M.J., University of Alberta, CA

In this study, we investigate the optical and structural properties of tilted columnar thin films composed of Alq3 in order to better understand the source of the in-plane birefringence exhibited by such films which is [...]

Fabrication and Characterization of 3D Square Spiral Photonic Crystals

Jensen M.O., Summers M.A., Brett M.J., University of Alberta, CA

Three-dimensional photonic crystals can be fabricated using the glancing angle thin film deposition technique (GLAD). These nanostructured thin films consist of a periodic array of micrometer-sized silicon square spirals, as proposed by O. Toader and [...]
