Abstract

This letter reports the fabrication and electrical characterization of mechanically flexible and low operating voltage transistors and logic gates (NOT, NAND, and NOR gates) using printed silicon nanomembranes and self-assembled nanodielectrics on thin plastic substrates. The transistors exhibit effective linear mobilities of ∼680 cm² /V s, on/off ratios > 10⁷, gate leakage current densities <2.8× 10-7 A/ cm², and subthreshold slopes ∼120 mV/decade. The inverters show voltage gains as high as 4.8. Simple digital logic gates (NAND and NOR gates) demonstrate the possible application of this materials combination in digital integrated circuits.
