Advanced methods in Glancing Angle Deposition to control thin film morphology, microstructure and texture
DownloadSpring 2014
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...

Fabrication and characterization of PZT nanorods and nanohexagons with applications in piezoelectric transducers
DownloadFall 2012
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...
