Abstract
We demonstrate key factors enabling mobility improvement at both low charge density and high density (>5×1012/cm2) in In0.7Ga0.3As quantum-well MOSFETs. We further show sub-threshold swing (SS) and on-current (Id) improvement in tunneling FETs (TFETs). By reducing EOT, optimizing the top-barrier/high-к interface, and confining carriers in In0.7Ga0.3As channel using In0.52Al0.48As bottom-barrier, SS and mobility of MOSFETs were improved from 152 to 99 mV/dec and from ∼2500 to ∼5000 cm2/V-s, respectively. TFETs achieved small SS (96 mV/dec) and high Id (55 µA/µm) due to low EOT and abrupt, vertical insitu grown III–V epitaxial junctions.
