High-Accuracy Contact Resistance Measurement Method for Liquid Metal by Considering Current-Density Distribution in Transfer Length Method Measurement.

ABSTRACT: Liquid metals (LMs) are used as stretchable conductors in various stretchable electronic devices. Moreover, such devices using Ga-based LMs have attracted considerable attention. Herein, we propose a method for accurately determining the contact resistance (R_c) between galinstan and Cu electrodes by considering the current-density distribution in transfer length method (TLM) measurement. Conventional TLM measurements assume that the sheet resistance of the metal electrode (R_she) is negligible compared with that of the object (R_sho), such as Si. However, this assumption may be problematic because the R_sho of Ga-based liquid metals (LMs) is close to the R_she. Therefore, we developed a method of applying
