Due to the small size of low-dimensional materials, traditional experimental methods can hardly meet the requirements of accurate measurement. This paper presented a method for measuring the thermal conductivity of low-dimensional materials based on DC heating. This method adopted a micro-machining process to prepare a measuring electrode in advance, and only needed to suspend the object (one-dimensional wire or two-dimensional film) on the electrodes and maintain close contact. Finally, a standard diameter of 20 μm platinum wire was used to verify the measurement accuracy of this method. The application and future development of thermal conductivity testing structures for low-dimensional materials were also prospected.
