Surface Passivation of GaAs Nanowires Ensembles for Photovoltaic Applications

Chia A.C.E., LaPierre R.R., McMaster University, CA

Fabrication, electrical characterization and analytical modeling of an AlInP-passivated GaAs NW ensemble is presented. Novel processing steps were used to fabricate NW ensemble devices which were subsequently characterized electrically and fit with an analytical model, [...]

Polymerization Passivation Strategies for the Stabilization of Energetic Aluminum Nanomaterials

Jelliss P.A., Thomas B.J., Patel A., Lloyd E., Guliants E.A., Bunker C.E., Buckner S.W., Saint Louis University, US

We are developing aluminum nanoparticle (Al NP) passivation strategies based on our established protocols for polymerization of epoxide molecules with a view to fabricating air-stable Al NPs with long shelf-lives. Additionally we have discovered that [...]

400-900 nm Light Emitting Silicon Nanoparticles

Liptak R.W., Pi X.D., Kortshagen U., Campbell S.A., University of Minnesota, US

A novel process has been developed to create an aerosol of passivated silicon nanoparticles that emit controlled colors from blue to the near IR. The emission is stable in air. This is the first ever [...]

Microcap Selective Packaging through Flip Chip Alignment

Chao C.H., Pan C.T., National Sun Yat-Sen University, TW

In this study, the technique of microcap selective bonding for 3-D microstructures using MEMS processes was presented. The flip-chip assembly was successfully demonstrated that the microcap transferred on the selective area of the host substrate [...]
