Extraction of Graphene-Titanium Contact Resistances using Transfer Length Measurement and a Curve-Fit Method
نویسندگان
چکیده
Graphene-metal contact resistance limits the performance of graphene-based electrical devices. In this work, we have fabricated both graphene field-effect transistors (GFET) and transfer length measurement (TLM) test devices with titanium contacts. The purpose of this work is to compare the contact resistances that can be numerically extracted from the GFETs and measured from the TLM structures. We also provide a brief review of the work done in the field to solve the contact resistance problem. Keywords—Contact resistance, graphene, TLM

متن کاملTuning thermal contact conductance at graphene-copper interface via surface nanoengineering.
Due to rapidly increasing power densities in nanoelectronics, efficient heat removal has become one of the most critical issues in thermal management and nanocircuit design. In this study, we report a surface nanoengineering design that can reduce the interfacial thermal resistance between graphene and copper substrate by 17%. Contrary to the conventional view that a rough surface tends to give...
