abstract = {pH sensitive properties of barium strontium titianate (BST)
high k thin films as alternative gate material for
field-effect capacitive (bio-) chemical sensors based on an
electrolyte-insulator semiconductor system have been
investigated. The BST films of different composition
(Ba0.3Sr0.69TiO3, Ba0.25Sr0.75TiO3 and MG doped
Ba0.8Sr0.2Mg0.1Ti0.9O3 were deposited by pulsed laser
deposition technique from targets farbicated by
self-propagating high-temperatures synthesis. The realised
sensors have been electrochemically characterised by means
of impedance-spectroscopy, capacitance-voltage and
constant-capacitance method. The sensors possess a
Nernstian-like pH sensitivity in the concentration range
between pH 3 and 11 with a response time of 5-10 s. An
equivalent circuit model for the BST-based capacitive
field-effect sensor is discussed.(C) 2010 WILEY-VCH Verlag
