Research Experience for Undergraduates: Materials Characterization

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
WSU has created a summer program for undergraduates from the Pacific Northwest to gain exposure to materials characterization methods. This interdisciplinary group of 10 students range from…

Oxide Fracture by Indentation to Measure Repassivation Kinetics

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
Many corrosion resistant materials, such as titanium and stainless steels, owe much of their corrosion resistance to the presence of a very thin passive film which isolates the metal from the…

Characterization of PZT/PLZT Multilayers

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
Thin ferroelctric films have been grown using solution deposition methods. Films of alternating layers of lead - zironcate - titanate and lead - lanthanum - zironcate - titanate have been grown,…

Undergraduate Research in Characterization of Advanced Materials

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
During the summer of 1999 the group of students, as part of an NSF REU summer program and a 1 credit course, visited PNNL to see first hand some equipment which is not available (or is significantly…

AES Study of Chemical Segregation in the Ti-Pt-PZT system for MEMS devices

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
In past investigations between WSU and EMSL, XPS analysis has provided evidence that Pb has diffused to the Ti/Pt interface in a Si/SiO2/Ti/Pt/PZT stack used in a MEMS microengine. Pb diffusion…

Texture, morphology, and stress in PZT thin films

Lead Institution
Washington State University
Principal Investigator
David Bahr
Project type
Exploratory Research
WSU is developing the P3 microengine, a MEMS device that utilizes a composite flexing membrane to generate power by converting mechanical energy to electrical energy. The membrane is made by lead-…
