- Dynamics of threshold voltage shifts in organic and amorphous silicon field-effect transistorsPublication . Mathijssen, S. G. J.; Colle, M.; Gomes, Henrique L.; Smits, E. C. P.; de Boer, B.; McCulloch, I.; Bobbert, P. A.; de Leeuw, D. M.The electrical instability of organic field-effect transistors is investigated. We observe that the threshold-voltage shift (see figure) shows a stretched-exponential time dependence under an applied gate bias. The activation energy of 0.6 eV is common for our and all other organic transistors reported so far. The constant activation energy supports charge trapping by residual water as the common origin.
- Ultralow Power Microfuses for Write-Once Read-Many Organic Memory ElementsPublication . de Brito, B. C.; Smits, E. C. P.; van Hal, P. A.; Geuns, T. C. T.; de Boer, B.; Lasance, C. J. M.; Gomes, Henrique L.; de Leeuw, D. M.Ultralow power microfuses for write-once read-many organic memory elements that rely on electrolysis of water rather than conventional Joule heating are presented. Gasses formed upon electrolysis cannot escape, the pressure rises, the top electrode delaminates and the electrical contact is lost. The voltage-driven fuses are ideally suited for low-end applications such as in electronic bar codes.
