This study determines the effect of incorporating black phosphorus (BP) nanosheets into poly(methyl methacrylate) (PMMA) on resistive switching (RS) mechanisms using the temperature-dependent current–voltage characteristics of gold/PMMA:BP/heavily doped p-type Si (p+-Si)/indium devices. A gold/PMMA:BP/p+-Si/indium device exhibits RS behavior, but a gold/PMMA/p+-Si/indium device exhibits set/reset–free current–voltage characteristics. The current in gold/PMMA:BP/p+-Si/indium devices is limited by ohmic conduction, the space charge or filled trap. Incorporating BP into PMMA results in a significant increase in the trap density for a PMMA:BP film, which increases the RS performance for gold/PMMA:BP/p+-Si/indium devices.
