| 520 | _ | _ | |a Light-addressable potentiometric sensors (LAPS) are semiconductor-
based potentiometric sensors, with the advantage to
detect the concentration of a chemical species in a liquid
solution above the sensor surface in a spatially resolved manner.
The addressing is achieved by a modulated and focused light
source illuminating the semiconductor and generating a
concentration-depending photocurrent. This work introduces
a LAPS set-up that is able to monitor the electrical impedance
in addition to the photocurrent. The impedance spectra of a
LAPS structure, with and without illumination, as well as the
frequency behaviour of the LAPS measurement are investigated.
The measurements are supported by electrical equivalent
circuits to explain the impedance and the LAPS-frequency
behaviour. The work investigates the influence of different
parameters on the frequency behaviour of the LAPS. Furthermore,
the phase shift of the photocurrent, the influence of
the surface potential as well as the changes of the sensor
impedance will be discussed |
