| Research Abstract |
The sensing of deoxyribonucleic acid solutions by capacitance-voltage measurements of a metal/micro-gap/semiconductor structure device has been demonstrated. The different concentrations of deoxyribonucleic acid solutions have been characterized from the change of the capacitance-voltage curve for the sensing device. A metal/insulator/gap/insulator/semiconductor structure device was sensitive to the ion concentration of the solution and had high sensitivity. It has been suggested that the change of capacitance-voltage characteristics reflects the change of the charge on the sensing silicon dioxide surface.
