1Effect of substrate miscut on the electron mobility in InSb(001) structures on Ge and Ge-on-insulator substrates显示文摘InSb epilayers and InSb/Al0.20In0.80Sb quantum wells were grown on Ge(001)substrates and Ge-on-insulator(GeOI)-on-Si(001)substrates by molecular beam epitaxy.Growth on both on-axis and 4°-off-axis substrate orientations was studied.Anti-phase domains were formed when InSb films were grown on on-axis substrates,but suppressed significantly by the use of 4°-off-axis substrates.Such off-axis substrates also reduced the densities of micro-twin defects and threading dislocations.The defect reduction resulted in an increase in the room-temperature electron mobility from 37,000 to 59,000 cm2/Vs in 4.0-lm-thick InSb epilayers and from 10,000 to20,000 cm2/Vs in 25-nm-thick InSb quantum wells on Ge(001)and GeOI-on-Si(001)substrates.M.C.Debnath T.D.Mishima M.B.Santos K.Hossain 2014Chinese Science Bulletin2014,59,4:0
