We demonstrated a nanowire gate-all-around (GAA) negative capacitance (NC) tunnel field-effect transistor (TFET) based on the GaAs/InN heterostructure using TCAD simulation. In gate stacking, we proposed tri-layer HfO<sub>2</sub>/TiO<sub>2</sub>/HfO<sub>2</sub> as high-K dielectric and hafnium zirconium oxide (HZO) ferroelectric (FE) layer. The GAA-TFET overcomes thermionic limitation (60 mV/decade) of conventional MOSFETs’ subthreshold swing (SS) thanks to its improved electrostatic...
Continuous downscaling of CMOS technology at the nanometer scale with conventional MOSFETs leads to short channel effects (SCE), increased subthreshold slope (SS), and leakage current, degrading performance ICs. We proposed a dual-source vertical tunnel field-effect transistor (TFET) steeper swing (SS) superior electrostatic control thanks quantum mechanical band-to-band tunneling. show that use GaSb/InGaAsSb/InAs heterostructure boosts tunneling rate in TFETs, resulting higher on-state...
Gate-all-around (GAA) field effect transistors (FETs) have appeared as one of the potential candidates for electrostatic integrity required to reduce MOSFETs minimum channel lengths. Meanwhile, negative capacitance ferroelectrics is known a remarkable quality enhancer in terms reducing sub-threshold slope (SS), supply voltage, and power consumption by utilizing gate voltage amplification phenomenon. In this work, combining these two phenomena we numerically design cylindrical GAA NCFET where...

The effect of channel length and width on the large small-signal parameters graphene field transistor have been explored using an analytical approach. In case faster saturation as well extremely high transit frequency, shows outstanding performance. From transfer curve, it is observed that there a positive shift Dirac point from voltage 0.15 V to 0.35 because reducing 440 nm 20 this curve depicts ambipolar behavior. Besides, found widening drain current increases maximum approximately 2.4 mA...
In graphene honeycomb structure, the phonon particles are strongly coupled with electrons, therefore any change in structure of changes electron-phonon (e-ph) interaction and consequently it has an impressive effect on electronic vibrational properties graphene.
