This paper reports the first known investigation of power dissipation and electrical breakdown in aerosol-jet-printed (AJP) graphene interconnects. The electrical performance of aerosol-jet printed (AJP) graphene was characterized using the Transmission Line Method (TLM). The electrical resistance decreased with increasing printing pass number (n); the lowest sheet resistance measured was 1.5 kΩ/sq. for n = 50. The role of thermal resistance (R_TH) in power dissipation was studied using a combination of electrical breakdown thermometry and infrared (IR) imaging. A simple lumped thermal model ([Formula: see text]) and COMSOL Multiphysics was used to extract the total R_TH, including interfaces. The R_TH of AJP graphene on Kapton is ~27 times greater than that of AJP graphene on Al₂O₃ with a corresponding breakdown current density 10 times less on Kapton versus Al₂O₃.

气溶胶喷射印刷石墨烯互连中的电传输和功耗。

本文报道了对气溶胶喷射印刷（AJP）石墨烯互连中的功耗和电击穿的首次已知研究。使用传输线方法（TLM）表征了气溶胶喷射印刷（AJP）石墨烯的电性能。电阻随着打印通过次数（n）的增加而降低；测得的最低薄层电阻为1.5kΩ/ sq。当n = 50时。结合电击穿测温法和红外（IR）成像研究了热阻（R _TH）在功耗中的作用。使用简单的集总热模型（[公式：参见文字]）和COMSOL Multiphysics提取包括界面在内的总R _TH。R _THKapton上的AJP石墨烯比Al ₂ O ₃上的AJP石墨烯高约27倍，相应的击穿电流密度在Kapton上比Al ₂ O ₃少10倍。
