Abstract:

Thisfinal report summarizes WSUs progress from 422015 to 09302016 on the project, Cross-linked Metal Particles CLMPs for Low-noise Bolometer Materials funded by the US Army Research Office under Contract W911NF-15-1-0117. We have successfully carried out the tasks listed in our proposal and gained significant insight into electrical transport in these CLMPs. We have successfully synthesized Au nanoparticles with different capping agents, grown good nanoparticlefilms, and measured temperature-dependent resistance of the nanoparticle films. In addition, working with Prof. A. J. Syllaios at the University of North Texas, we have started characterizing the noise performance of the nanoparticle films. Our results indicate that the CLMPs can simultaneously have a high temperature coefficient of resistivity and a low noise, and therefore have a great potential in the microbolometer technology.
