Abstract :
This paper demonstrates for the first time the use of microplasma to perform AND, OR, and XOR logic operations. The logic circuits are implemented similar to diode-resistor logic. Output voltages are in the range of 5-40 V and can be modified by varying the load resistor. The active area of the microplasma device is just 50 μm × 5 μm. The small interelectrode gap kept breakdown voltage to ~250 V when operated in He gas at atmospheric pressure. The use of plasma as a source of free carriers is also demonstrated, with free carriers available up to 500-μm away from plasma.
