To explore the origins of the degradation, we employ nonlocal B3LYP hybrid functional to study arsenic related defects in ZrO2. Via band alignments between the OaAs and ZrO2, we are able to determine the defect formation energy in the GaAs relative to the ZrO2 band gap and assess how they will affect the device performance. Arsenic at the interstitial site serves as a source of positive fixed charge while at the oxygen or zirconium substitutional site changes its charge state within the band gap of GaAs. Moreover, it is found that arsenic related defects produce conduction band offset reduction and gap states, which will increase the gate leakage current.展开更多

This is the first legally binding international instrument dedi- cated to the protection of the rights of persons with disabilities and the latest effort by the international community to protect and promote the human fights of persons with disabilities. The Convention clarifies the rights of per- sons with disabilities to participate in political, economic, social, cultural and civil life and stresses that all signatory parties have the obligation and duties to ensure that persons with disabilities really enioy the same human rights,展开更多
