Abstract
A solid state chemical sensing device is described in which a chemically sensitive electrode, and at least one diamond film are deposited on a conductive or insulating substrate. The device forms a sensing structure in which conduction of current through the device in the presence of a target chemical is dominated by space charged limited current, thereby providing enhanced sensitivity and selectivity.
