In this paper, the RF power change effect on the structural, optical and electrical properties of CuO thin films prepared by RF reactive magnetron sputtering deposited on glass substrates are studied. At first, the thin films are prepared at 150, 280, 310 and 340W respectively. Then, the films are characterized by XRD, AFM, Uv-visible and four-point probe analysis respectively. The results show...
Four-point probe characterization is a standard method for studying the electrical properties of solids and thin films. The probe spacing in four-point probe technique has to be reduced to micro-scale to obtain expected surface sensitivity and spatial resolution. Therefore, microscopic four-point probes (M4PPs) need to be combined with some microscopy techniques. Two types of M4PPs systems have...
This article briefly elaborated the basic concepts of the probe vacillated at testing a large silicon wafer with square four point probe equipment. The importance of the micro-area’s sheet resistance is discussed and the basic principles of four point probe measurement technology are analyzed. Some factors that affect the measurement accuracy are studied, and interference can be avoided while m...
