Analysis and study of geometrical variability on the performance of junctionless tunneling field effect transistors: Advantage or deficiency?

This study investigates geometrical variability on the sensitivity of the junctionless tunneling field effect transistor (JLTFET) and Heterostructure JLTFET (HJLTFET) performance. We consider the transistor gate dielectric thickness as one of the main variation sources. The impacts of variations on the analog and digital performance of the devices are calculated by using computer aided design […]

Combined effects of pressure, temperature, and magnetic field on the ground state of donor impurities in a GaAs/AlGaAs quantum heterostructure

In the present work, the exact diagonalization method had been implemented to calculate the ground state energy of shallow donor impurity located at finite distance along the growth axis in GaAs/AlGaAs heterostructure in the presence of a magnetic field taken to be along z direction. The impurity binding energy of the ground state had been […]

Representation of a nanoscale heterostructure dual material gate JL-FET with NDR characteristics

In this paper, we propose a new heterostructure dual material gate junctionless field-effect transistor (H-DMG-JLFET), with negative differential resistance (NDR) characteristic. The drain and channel material are silicon and source material is germanium. The gate electrode near the source is larger. A dual gate material technique is used to achieve upward band bending in order […]
