Abstract Lead-free epitaxial (K 0.47 Na 0.53 )NbO 3 (KNN) thin films were fabricated on (001)SrRuO /Pt/ZrO 2 /Si substrates by RF magnetron sputtering at 650 °C and post-annealed the same a rapid thermal annealing (RTA) process. The crystal structure of KNN changed RTA, i.e. lattice parameter c in out-of-plane direction decreased instead an increase in-plane direction. displacement–electric fie...

Title of dissertation: PIEZOELECTRIC MICROBEAM RESONATORS BASED ON EPITAXIAL Al0.3Ga0.7As FILMS Lihua Li, Doctor of Philosophy, 2005 Dissertation directed by: Professor Don DeVoe Department of Mechanical Engineering In this work, piezoelectric resonators based on single crystal Al0.3Ga0.7As films are implemented. The combination of Si doped Al0.3Ga0.7As as electrode layers and moderate piezoele...

In this series a pictorial quiz pertaining to identification of normal anatomical structures and landmarks at a given level on the computed tomography (CT) is presented. An image depicting normal anatomy is followed by a series of images showing different pathologies. Readers are expected to identify and appreciate variation and changes in the normal anatomy in presence of a given pathology. Th...
