Programme
13.30: Pieter Stroeve: (Bio)materials
14.30: Ernst Sudholter WUR TBA: Silicon surface modification, a possible route ty hybrid organic semiconductor field effecttransistors
The silicon hydride surface obtained after etching silicon with hydrogen fluoride can be conveniently modified with ?-functionalised alkenes and alkynes. The formed monolayers are covalently bound via silicon-carbon bonds. These bonds are very stable and the monolayer is closely packed preventing surface oxidation. Different procedures for obtaining highly ordered monolayers will be discussed.
Alkyl modified silicon has shown to passivate silicon surfaces, which is beneficial for solar cell applications. The potential of the method to develop biosensors with electrical read-out (the so called HOSFET, hybrid organic semiconductor field effect transisitor), will be discussed based on recent electrical characterizations and model simulations.
