![]() ![]() Each device may have one or more carbon nanotubes with user-specified chirality, and the effects of channel length scaling can be accurately modeled down to 20nm. This study provides a promising approach for developing next-generation energy-efficient electronic devices and ultralow-power applications. The Stanford University CNFET Model is a SPICE-compatible compact model which describes enhancement-mode, unipolar MOSFETs with semiconducting single-walled carbon nanotubes as channels. Furthermore, compared to previously reported threshold-switching devices, our device demonstrated hysteresis-free switching characteristics.

We obtained repetitive operation with low SS (32.8 mV dec −1) at room temperature, along with low dielectric injection efficiency (10 −6), through a structural design with separation of the conducting region, which determines on-state carrier transport, and the steep-switching region where the transition from off- to on-state occurs via impact ionization. In this study, we presented an impact-ionization-based threshold switching field-effect transistor (I 2S-FET) fabricated with a serial connection of a MoS 2 FET and WSe 2 impact ionization-based threshold switch (I 2S). ![]() However, most of them cannot retain steep switching at room temperature, and device performance degradation issues caused by impact ionization-induced hot carriers have not been structurally addressed. ![]() Recently, two-dimensional material-based impact ionization transistors with various structures have been reported with the advantages of a low critical electric field and a unique quantum confinement effect.

A steep switching device with a low subthreshold swing (SS) that overcomes the fundamental Boltzmann limit ( kT/ q) is required to efficiently process a continuously increasing amount of data. 3) Field Effect Transistors (FETs) - This is the primary logic transistor. ![]()
