Abstract
The project deals with the development and study of the integration of quartz crystal microbalance (QCM) with field-effect transistors (FET) in one diamond (D) platform for dual-sensing of (bio-) molecules. Such a unique and novel sensor, which combines acoustic (mass) and electrical (surface charge) detections, requires the involvement of interdisciplinary research and complex technological facilities, which are complementary covered by the Slovak and Czech research teams. We will systematically study i) the influence of mechanical vibrations (QCM and SAW GaN) on the electrical conductivity of 2D hole channel in H-diamond, ii) the influence of diamond properties on particular functions of D-QCM and D-FET, and iii) processes during the detection of (bio-) molecules by diamond QCM-FET device. The cross-validation of processes with dual-sensing devices by implementing diamond as a functional layer represents a natural bridge between the organic and inorganic world that will move forward in understanding interactions during adhesion of (bio) molecules on semiconductor materials.
