Author ProfileAbstract
This study analyses various factors that affect the threshold voltage of
MOSFETs at deep cryogenic temperatures, including band-tail state,
field-assisted ionization, and interface traps. Based on the analysis, a
new model is developed for Si-based MOSFETs covering a wide temperature
range from 10K to 300 K. The model's validity is confirmed through
experiments of bulk silicon and FDSOI MOSFETs.11 Nov 2024Submitted to International Journal of Numerical Modelling: Electronic Networks, Devices and Fields 12 Nov 2024Submission Checks Completed
