Temperature dependence of electronic behaviors in quantum dimension junctionless thin-film transistor

Abstract

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 fitting experimental data exhibits the quantum confinement effect, indicating greater suppression of Ioff than that in JL planar TFTs. The measured ∂Vth∂T of −1.34 mV/°C in JL GAA nanosheet TFTs has smaller temperature dependence than that of −5.01 mV/°C in JL planar TFTs.

Analysis of the Electrical Parameters of SOI Junctionless Nanowire Transistors at High Temperatures

“…And comparatively the on current shows little variation with the temperature. Similar results show that the degradation of the off current with temperature is also much larger than the degradation of the on current [1,7,15,20]. Fig.…”

“…The effects of the high temperatures on the electrical characteristics of the triple-gate junctionless nanowire transistors have been reported in [1,7,[12][13][14][15][16][17][18]. In these works, several aspects of the junctionless nanowire transistors were studied as a function of the high temperature.…”

“…The characteristics of junctionless nanosheets as a function of the temperature were analyzed in [15]. Electric characteristics like DIBL and ION/IOFF were analyzed in [1] and the impact of the temperature on the off current was also analyzed in [7,15,20]. In [16] it was presented a simulated study on the characteristics of junctionless transistors for short channel devices.…”

A novel dielectrophoresis potential spectroscopy for colloidal nanoparticles

“…However, existing experiments have so far not been able to resolve the differences of the predictions by those theories discussed above. The main reason is that the DEP forces of nanoparticles are so small (because of ) that existing methods can hardly detect them. The optical tweezer‐based DEP force spectroscopy , useful for measuring micron‐sized particles, is not so suitable for measuring nanoparticles because it is difficult to ensure only one nanoparticle in the optical trap.…”
