Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and textureDownload
Structuring of material on the nanoscale is enabling new functional materials and improving existing technologies. Glancing angle deposition (GLAD) is a physical vapor deposition technique that enables thin film fabrication with engineered columnar structures on the (10 to 100) nm scales. In this...
The glancing angle deposition (GLAD) technique is now used by over one hundred research groups, each requiring a fundamental understanding of and new techniques for modulating the properties of GLAD in order to optimize their results. In this thesis, the structural characteristics of...
Glancing angle deposition (GLAD) is a thin film fabrication technique capable of creating arrays of nanocolumns from numerous materials. Optimizing these films for applications requires an understanding of their growth, prompting research into the columns’ growth scaling behaviour. Columns are...
Fabrication and characterization of PZT nanorods and nanohexagons with applications in piezoelectric transducersDownload
All ultrasound devices/sensors use piezoelectric transducers to generate/receive ultrasound. These transducers are made of Pb (Zr0.53Ti0.47) O3 (PZT) materials. In this article, we report a new way of fabricating PZT material with interesting nanorod and nanohexagon shapes. The PZT nanohexagons...
Electron Beam Lithography (EBL) is a powerful tool for structuring materials at the deep nanoscale. Modeling and simulation of electron-beam interactions at this length scale is vital to understanding and optimizing nanofabrication using EBL. The low to high voltage (5 keV – 100 keV) regimes of...
Molecular separations using nanostructured porous thin films fabricated by glancing angle depositionDownload
Biomolecular separation techniques are an enabling technology that indirectly influence many aspects of our lives. Advances have led to faster analyses, reduced costs, higher specificity, and new analytical techniques, impacting areas such as health care, environmental monitoring, polymer...
Extending electronic devices beyond the limitations of current micro-electronics manufacturing will require detailed knowledge of how to make contacts to semiconductor surfaces. In this work, we investigated several methods by which such connections to silicon surfaces could be achieved. Scanning...
The lead sulfide colloidal quantum dots (PbS CQD) solar cell has attracted wide attention in recent years for its facile fabrication process and low cost. However, the power conversion efficiency (PCE) of PbS CQD cell is still low due to the trade-off between light absorption and carrier...
Organic photovoltaic cells (OPVs)are promising devices for inexpensive power generation from sunlight. Organic semiconductors, the basic materials for OPVs, can be fabricated using a broad range of fabrication technologies from vapor deposition to solution processing. Upon light absorption,...
