Sensitivity of encapsulated diamond-protein transistor renewed by low temperature hydrogen plasma
Original language description
We study effects of low temperature hydrogen plasma treatment (200 ? 300 °C) done in two different microwave plasma reactors (linear and focused plasma) on functionality of diamond solution-gated field-effect transistors (FET) covered with various encapsulation (ma-P, OFPR, SU8, Si3N4) and with proteins adsorbed on the gate. Three-dimensional transistor microstructures (20 ?m) are made of nanocrystalline hydrogen terminated intrinsic diamond that is grown on Si/SiO2 substrates by selective seeding and microwave plasma CVD growth. The hydrogen-plasma treatment in linear plasma system at 200 °C removes the proteins from the gate as evidenced by atomic force microscopy, keeps the FET fully operational, and renews solution-gated FET sensitivity to proteinadsorption (unlike rinsing in solutions) as evidenced by reproducible shift of transfer characteristics by -30 mV.
