- Electrical characteristics of n-type vertically stacked nanowires operating up to 600 K(2022-08-05) MARINIELLO, G.; BARRAUD, S.; VINET, M.; CASSE, M.; FAYNOT, O.; CALCADE, J.; Marcelo Antonio Pavanello© 2022 Elsevier LtdThis paper aims at analyzing the electrical characteristics of n-type vertically stacked nanowires with variable fin width, operating in the temperature range of 300–600 K. Basic electrical parameters, such as threshold voltage, subthreshold slope, and carrier mobility are extracted in the linear region, whereas the transconductance, output conductance, and intrinsic voltage gain are extracted in saturation, to access some of device's analog figures of merit. Also, it has been analyzed the DIBL, GIDL, Ion, and Ioff. currents.
- Analog characteristics of n-type vertically stacked nanowires(2021) MARINIELLO, G.; CARVALHO, C. A. B. D.; CARDOSO, PAZ, B.; BARRAUD, S.; VINET, M.; FAYNOT, O.; Marcelo Antonio Pavanello© 2021This paper presents the fundamental analog figures of merit, such as the transconductance, output conductance, transconductance over drain current ratio, intrinsic voltage gain and harmonic distortion (or non-linearity), of n-type vertically stacked nanowires with variable fin width and channel length. To have a physical insight on the results, the basic electrical parameters such as threshold voltage, subthreshold slope and low field electron mobility of the analyzed transistors were also studied. The studied analog parameters are presented in function of the transconductance over drain current, to allow for the comparison at the same inversion level.
- Study of silicon n- and p-FET SOI nanowires concerning analog performance down to 100 K(2017) Paz B.C.; Casse M.; Barraud S.; Reimbold G.; Vinet M.; Faynot O.; Pavanello M.A.© 2016 Elsevier LtdThis work presents an analysis of the performance of silicon triple gate SOI nanowires aiming the investigation of analog parameters for both long and short channel n-type and p-MOSFETs. Several nanowires with fin width as narrow as 9.5 nm up to quasi-planar MOSFETs 10 μm-wide are analyzed. The fin width influence on the analog parameters is studied for n-type and p-MOSFETs with channel lengths of 10 μm and 40 nm, at room temperature. The temperature influence is analyzed on the analog performance down to 100 K for long channel n-MOSFETs by comparing the quasi-planar device to the nanowire with fin width of 14.5 nm. The intrinsic voltage gain, transconductance and output conductance are the most important figures of merit in this work. An explicit correlation between these figures of merit and the mobility behavior with temperature is demonstrated.
