Electic-Field-Enhanced Emission and Annealing Behaviour of Electron Traps Introduced in n-Si by Low-Energy He Ion Bombardment
The isochronal annealing and electric-field-enhanced emission properties of three defects (EHe203, EHe584 and EHe211), observed in low-energy He-ion bombarded n-Si, were studied using deep level transient spectroscopy. EHe203 (EC - 0.20 eV) and EHe584 (EC - 0.58 eV) were thermally stable up to ∼400°C after which their removal was accompanied by the introduction of a secondary defect EHe211 (EC - 0.21 eV). EHe211 was thermally stable at 650°C. The emission rate of EHe203 was significant for...[Show more]
