    Diamond field-effect transistors (FETs) operate in electrolyte solutions having a wide pH range of 1-13. The FETs have been fabricated using a p-type surface conductive layer, where the diamond surface is exposed directly to the electrolyte solutions. From the drain current-gate voltage (I ds-Vgs) characteristics of the FETs, it appears that the threshold voltages of the FETs are independent of the pH value of the solution. In Cl- ionic solutions, however, the threshold voltages shift approximately 30 mV with a one-order-of-magnitude change of molar concentration of Cl- ions. This sensitivity of the FET to Cl- ion's concrentration is observed in the 10-110-6M range of potassium chloride (KC1) solutions
