Ink-jet printed ZnO Nanoparticle Thin Films for Sensing Applications

Hartner S., Khalil A.S.G., Ali M., Winterer M., Wiggers H., University Duisburg-Essen, DE

Stable aqueous dispersions of ZnO NPs are successfully prepared with a new polymeric stabilizer. The dispersions are stable for at least 2 months without any observable sedimentation. The zeta potential and the size of the [...]

Electrical Properties of Functionalized Silicon Nanoparticles

Hartner S., Gupta A., Wiggers H., University Duisburg-Essen, DE

Phosphorous-doped as well as undoped Si-NPs with a mean particle diameter of about 50 nm were synthesized in a microwave plasma. The natural oxide was removed by etching the particles with hydrofluoric acid. In order [...]
