In this work, we present a gate-all-around (GAA) low-temperature poly-Si nanowire (NW) junctionless device with TiN/Al.

An analytical model of the threshold voltage variance induced by random dopant fluctuations (RDF) in junctionless (JL) FETs is derived for both cylindrical nanowire (NW) and planar double-gate (DG) structures considering only the device electrostatics in subthreshold. The model results are shown to be in reasonable agreement with TCAD simulations for different gate lengths and device parameters...

Abstract: In this paper, a novel tunnel field effect transistor (TFET) is introduced, thatdue to its superior gate controllability, can be considered as a promising candidate forthe conventional TFET. The proposed electrically doped heterojunction TFET(EDHJTFET) has a 3D core-shell nanotube structure with external and internal gatessurrounding the channel that employs el...

In this paper it has been demonstrated that a shielded channel made by varying the side gate length in silicon-on-nothing junctionless transistor not only improves short effect but also improve performance of CMOS circuits device. The proposed device dual stack silicon on nothing (SCDGSSONJLT) drain induced barrier lowering (DIBL), cut-off frequency and subthreshold slope are improved 20%, 39% ...

In this article, the particle irradiation effect of a lightly doped Gaussian source heterostructure junctionless tunnel field-effect transistor (DMG-GDS-HJLTFET) is discussed. phenomenon, heavy ion produces series electron-hole pairs along incident track, and then generated transient current can overturn logical state device when number large enough. single-particle DMG-GDS-HJLTFET, carried ene...

The high temperature dependence of junctionless (JL) gate-all-around (GAA) poly-Si thin-film transistors (TFTs) with 2-nm-thick nanosheet channel is compared with that of JL planar TFTs. The variation of SS with temperature for JL GAA TFTs is close to the theoretical value (0.2 mV/dec/K), owing to the oxidation process to form a 2-nm-thick channel. The bandgap of 1.35 eV in JL GAA TFTs by fitti...
