摘要：
Erbium doped Si epilayers grown by the liquid phase epitaxy (LPE) technique have been studied by means of optical and electrical characterization methods. Their optical emisssion at lambda=1.54 mu m has been observed at T=2K with photoluminescence measurements after a thermal treatment. Junction spectroscopy analyses have identified the deep traps present at the epilayer-substrate interface and in the bulk substrate. A tentative attribution of their origin is here presented.
