Assessment of paper-based MoS2 FET for Physically Unclonable Functions

Two-dimensional (2D) materials are recognized as a promising beyond-CMOS technology thanks to their attractive electrical and mechanical properties, which make them particularly suitable for flexible electronics. This work investigates molybdenum disulfide (MoS2) based field-effect transistors (FETs) fabricated on paper substrate to design hardware-security primitives such as Physically Unclonable Functions (PUFs). Circuit simulations have been performed by using a look-up-table (LUT) based Verilog-A model calibrated on electrical measurements of fabricated devices. Obtained results prove the potential of paper-based MoS2 FETs as building blocks for next-generation flexible electronics in the field of hardware security.
