Nanocrystalline diamond films for electronic monitoring of gas and organic molecules

Nowadays, implementation of specific materials for (bio) sensors is one of the most rapidly developing micro-electronic field. Synthetic diamond thin films exhibit an extraordinary combination of intrinsic properties which make it an attractive material for investigation of solid state interaction with (bio) molecules or complex biological systems. Hydrogen terminated intrinsic diamond films reveal a phenomenological property - induced p-type surface conductivity which has been found as suitable for fabrication of various electronic devices, mainly impedance elements and field effect transistors. This study draws on research conducted by employing hydrogen terminated nanocrystalline diamond as the functional layer for (bio) sensoric uses and point out recent models for the detection principles.
