Fractal dimension of semiconducting fractal sensors

Metal oxides are used for analysis of gas in the air in nano-dispersion semiconducting sensors developed in recent years. The fractal dimension of such a semiconductor sufficiently influences the character of the electrical conductivity and hence the sensitivity and operating speed of the sensor. The work considers the fractal properties of the structure of the sensitive weight of a semiconductor sensitive element (SE) for the detection of dangerous gas molecules. The way of defining the fractal dimension of the sensitive weight is shown by means of resistance measurement at high frequencies.
