  • Abstract
    A velocity-field study of holes in partially strain compensated Si 0.793Ge0.2C0.007 p-MOSFET devices with channel lengths ranging from 0.8 to 10 μm has been carried out. A very high effective hole velocity, 1.1 × 107 cm/s attributed to the onset of velocity overshoot in SiGeC p-MOSFETs, is reported. Significant improvement in effective hole velocity of Si0.793Ge0.2C0.007, compared to that of a binary Si0.8Ge0.2 device, is observed. this being due to C-induced strain stabilisation in the metastable SiGe layer
