Defect Reduction and Its Mechanism of Selective Ge Epitaxy in Trenches on Si(001) Substrates using Aspect Ratio Trap**
Defect-free germanium has been demonstrated in SiO2 trenches on silicon via aspect ratio trap**, whereby defects arising from lattice mismatch are trapped by laterally confining sidewalls. Results were achieved...
