摘要

为测量材料的电阻率，设计并制作了一个简单的 DIY 仪器。该工具携带方便，操作简单，学生/新研究人员只需花费最少的时间和原材料，就能制作出自己的仪器。仪器的弹簧式四点探针有助于在样品表面和探针之间提供良好的电接触。通过将电阻率数据与文献值进行比较，对其可靠性进行了检验，测量结果与之前的数据十分吻合。该仪器适用于从室温到 ∼100 °C 的测量。

A simple DIY electrical resistivity apparatus for students

A simple do-it-yourself (DIY) apparatus is designed and built for the measurement of the electrical resistivity of materials. The tool is portable and easy to operate, and students/new researchers can build their own apparatus with a minimum amount of time and raw materials. The apparatus’ spring-loaded four-point probes help provide a good electrical contact between the sample surface and the probes. It has been checked for its reliability by comparing the resistivity data with literature values and the measurements match well with the previous data. The apparatus is suitable for measurements from room temperature to ∼100 °C.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
