Kobayashi, N. Matsuo, A. Heya, S. Yokoyama Engineering, Materials Science Web27 Oct 2024 · The hump behavior of gate-normal nanowire tunnel field-effect transistors (NWTFETs) is investigated by using a three-dimensional technology computer-aided design (TCAD) simulation. The simulation results show that the hump behavior degrades the subthreshold swing (SS) and on-current (Ion) because the corners and sides of nanowires …
Web1 Nov 2002 · In the ultra-thin LOCOS devices, the subthreshold swing is constant with width, around 70 mV/dec showing a minor influence of FBEs. But the swing drops below 60 mV/dec in the thicker films (between 40 and 55 mV/dec, depending on the specific width and thickness values) due to the appearance of FBEs.

Webas subthreshold hump (hump) and the reverse narrow channel effect (RNCE) or the reverse narrow width effect (RNWE), which are caused by crowding of the gate fringing field at the STI corner.1–4) Therefore, much studies have been striven to reduce RNCE and the hump characteristics by controlling There are two main causes for the abnormal hump behavior owing to the device driving stress. The first is the constant voltage/current driving stress applied at the gate electrode, which is similar in character to that of the pixel driving transistors in the OLED display.
