We have demonstrated reduced 1/f low-frequency noise in sub-mum metamorphic high Ge content p-Si0.3Ge0.7 metal-oxide-semiconductor field-effect transistors (MOSFETs) at 293 K. Three times lower normalized power spectral density (NPSD) S-I D/I-D(2) of drain current fluctuations over the 1-100 Hz range at V-DS=-50 mV and V-G-V-th=-1.5 V was measured for a 0.55 mum effective gate length p-Si0.3Ge0.7 MOSFET compared with a p-Si MOSFET. Performed quantitative analysis clearly demonstrates the importance of carrier number fluctuations and correlated mobility fluctuations (CMFs) components of 1/f noise for p-Si surface channel MOSFETs, and the absence of CMFs for p-Si0.3Ge0.7 buried channel MOSFETs. This explains the reduced NPSD for p-Si0.3Ge0.7 MOSFETs in strong inversion. (C) 2004 American Institute of Physics.
