High hole mobility front-gate InAs/InGaSb-OI single structure CMOS on Si

We have demonstrated the front-gate (FG) III-V single structure CMOS using ultra-thin body (UTB) InAs/InGaSb on insulator (-OI) on Si substrates with high hole mobility (μ<sub>eff</sub>) of 240 cm<sup>2</sup>V<sup>-1</sup>s<sup>-1</sup>. We have found that the μ<sub>eff</sub> is enhanced by the buffered-HF (BHF)-cleaned InAs MOS interfaces, Ni alloy S/D, and the InAs/strained InGaSb-OI hetero-interface channel. The CMOS operation using FG InAs/InGaSb-OI n/p-MOSFETs has been realized.
