We present a scheme for measuring the resistance of a single Bi nanowire using a 4-point measurement technique. The nanowires are found to have a 7nm thick oxide layer which causes very high contact resistance when electrodes are patterned on top of the nanowires. The oxide is found to be ...
开尔文四线检测 Kelvin (4-wire) resistance measurement 开尔文四线检测(Kelvin Four-terminal sensing)也被称之为四端子检测(4T检测, 4T sensing)、四线检测或4点探针法,它是一种电阻抗测量技术,使用单独的对载电流和电压检测电极,相比传统的两个终端( 2T)传感能够进行更精确的测量。开尔文四线检测被用于一些欧姆...

PURPOSE:To provide a probe head for measuring four-terminal resistance, being employed when the resistance of a printed wiring board or the like is measured by four-terminal method, which allows measurement of resistance even of a high density printed wiring board or a printed wiring board having...
Current measurement using a shunt resistor and voltmeter is particularly well-suited for applications involving particularly large magnitudes of current. In such applications, the shunt resistor’s resistance will likely be in the order of milliohms or microohms, so that only a modest amount of volta...
Kelvin (4-wire) resistance measurement Suppose we wished to measure the resistance of some component located a significant distance away from our ohmmeter. Such a scenario would be problematic, because an ohmmeter measuresallresistance in the circuit loop, which includes the resistance of the wires ...
