“…9 Enhancing the BTBT rate of direct gap Ge 1−x Sn x alloys is important for high-performance TFETs in application. The direct gap BTBT generation rate G can be described by Kane's model in the form 33,34 …”
Direct gap Ge1−xSnx alloys under [100] and [110] uniaxial strain are comprehensively investigated by theoretical calculations using the nonlocal empirical pseudopotential method (EPM). It is shown that [100] uniaxial tensile strain aids indirect-to-direct gap transition in Ge1−xSnx alloys. The Γ electron effective mass along the optimal direction under [110] uniaxial strain is smaller than those under [100] uniaxial strain and (001) biaxial strain. Additionally, the direct tunneling gap is smallest along the strain-perpendicular direction under [110] uniaxial tensile strain, resulting in a maximum direct band-to-band tunneling generation rate. An optimal [110] uniaxial tensile strain is favorable for high-performance direct gap Ge1−xSnx electronic devices.
“…Kane derived a familiar equation for Zener's BTBT, [36] which yields the third guideline. The equation for tunneling rate G, which is proportional to I, is expressed as [32,36] …”
Section: Overview Of State-of-the-art Tfet Researchmentioning
The tunnel field-effect transistor (TFET) is one of the candidates replacing conventional metal-oxide-semiconductor field-effect transistors to realize low-power-consumption large-scale integration (LSI). The most significant issue in the practical application of TFETs concerns their low tunneling current. Si is an indirect-gap material having a low band-to-band tunneling probability and is not favored for the channel. However, a new technology to enhance tunneling current in Si-TFETs utilizing the isoelectronic trap (IET) technology was recently proposed. IET technology provides a new approach to realize low-power-consumption LSIs with TFETs. The present paper reviews the state-of-the-art research and future prospects of Si-TFETs with IET technology.
