Mechanical, electrical, long-term, and environmental reliabilities a Images of the stacked 3-T device under bending test (white dotted area is magnified) and its saturation transfer characteristics as bent on a curved surface (scale bars in the top and bottom images are 1 cm and 1 mm, respectively). b Shift of the saturation transfer characteristics of the printed stand-alone complementary transistors after electrical bias stress for 10,000 s (at VGS = VDS = 5 V for the n-type and −5 V for the p-type). c Year-long observation on the carrier mobilities and threshold voltages of the stand-alone and stacked 2-T devices (μn, μp: carrier mobility, μn0, μp0: initial carrier mobility, VTH,n, VTH,p: threshold voltage, error bars represent standard deviation). d Shift of the saturation transfer characteristics of the complementary dual-gate transistors under consecutive five thermal stress steps. e Shift of the saturation transfer characteristics of the complementary dual-gate transistors under a humid environment (90% rh, 30 °C) for 24 h (rh: relative humidity)
