Abstract
The first demonstration of an integrated circuit using high mobility p-channel modulation doped field effect transistors (MODFETs) is reported. A static frequency divider was fabricated on Si0.7Ge0.3/Si0.2Ge0.8/Si0.7Ge0.3 strained heterostructures grown epitaxially on Si using ultra-high vacuum chemical vapour deposition; divide-by-two operation was achieved for clock frequencies of up to 2.9 GHz.
