Explicit form of the geometric factor for a thin disk’s resistivity measurement
چکیده انگلیسی

The geometric factor for the resistivity measurement of a thin disk, given in a previous work as a slowly converging series, is reworked and reduced to a simple form. On the other hand, the correction, when contacts are assumed of vanishing width, is also calculated analytically and discussed. It is found not to exceed 1.5% when λ, the ratio of distances between potential contacts and current contacts, is equal to 1. Our new expression is applied to determine the room temperature resistivity of two metallic thin disks.
