Effect of the Thickness of Insulator Polymeric Films on the Memory Behavior: The Case of the Polymethylmethacrylate and the Polystyrene
Figure 5
AFM images of the PMMA films over glass substrates with a thickness of (a) 9 nm, which corresponds to I-V ohmic response and (b) 15 nm, which corresponds to I-V response with two ON states.
