Origin of temperature dependent conduction of current from n-4H-SiC into silicon dioxide films at high electric fields

Applied Physics Letters (2018)

Xiang An Xingliang Xu Lin Zhang Zhiqiang Li Jun‐Tao Li

The conduction of current from n-4H-SiC into pyrogenic and dry oxidized films is studied. Anomalous current conduction was observed at a high electric field above 8 MV/cm for dry oxidized metal-oxide-semiconductor (MOS) capacitors, which cannot be interpreted in the framework of pure Fowler-Nordheim tunneling. The temperature-dependent current measurement and density of interface trap estimated from the hi-lo method for the SiO2/4H-SiC interface revealed that the combined current conduction of Fowler-Nordheim and Poole-Frenkel emission is responsible for the current conduction in both pyrogenic and dry oxidized MOS capacitors. Furthermore, the origin of temperature dependent current conduction is the Poole-Frenkel emission via the carbon pair defect trap level at 1.3 eV below the conduction band edge of SiO2. In addition, with the dry oxidized capacitors, the enhanced temperature dependent current above 8 MV/cm is attributed to the PF emission via a trap level at 1.47 eV below the conduction band edge of SiO2, which corresponds to another configuration of a carbon pair defect in SiO2 films.

Microporous organic hydroxyl-functionalized polybenzotriazole for encouraging CO2 capture and separation

RSC Advances (2019)

Qiang Yin Chunlin Lu Shuai Zhang Meifang Liu Kai Du

We report a mild, hydroxyl functionalized and thermal stable benzotriazole-based aerogel (HO-PBTA), which is inspired by phenolic resin chemistry. Taking advantage of the synergistic adsorption interactions between hydroxy-benzotriazole and CO2, and the phobic effect between benzotriazole and nitrogen (N2), the CO2 uptake capacity of the HO-PBTA reaches an encouraging level (6.41 mmol g-1 at 1.0 bar and 273 K) with high selectivity (CO2/N2 = 76 at 273 K).

Impact of neutron radiation induced defects on the surge current robustness of silicon carbide P‐intrinsic‐N diodes

Electron (2024)

Haoshu Tan Lin Zhang Zhiqiang Li Jun Tao Li Peng Dong

Abstract Surge current (SC) capability is one of the main aspects of reliability for silicon carbide (SiC) power devices. In this work, the influences of neutron radiation‐induced defects on the SC capability and reliability of SiC P‐intrinsic‐N (PiN) diodes were comprehensively investigated. It was found that the surge capability of the diodes can be deteriorated even under the slightly enhanced formation of carbon‐vacancy‐related Z 1/2 and EH 6/7 defects introduced by neutron irradiation. Surprisingly, it was found that the forward voltage ( V F ) decreases with the increased SC and the stress cycles in the irradiated diodes, which is usually found to increase under the SC tests and attributed to the bipolar degradation (BPD). By using technology computer‐aided design simulation and deep‐level transient spectroscopy characterization, it was found that the significant self‐heating during surge stress leads to the annealing effect on the Z 1/2 defects through the promoted recombination with the nearest and second neighbor carbon interstitials injected by irradiation, which thus plays a dominant role in the decrease of V F over the BPD.

The Influence of Noise in the Super-Resolution Reconstruction of Structured Illumination Microscopy

Journal of Physics Conference Series (2021)

Jinxi Bai Zhendong Shi Hua Ma Lijia Liu Lin Zhang

Abstract As one of the mainstream super-resolution imaging technologies, structured illumination microscopy (SIM) is popular for its fast imaging speed and simple optical path structure. Spectrum separation is a key step in the reconstruction of super-resolution images. However, in the process of imaging, the unavoidable noise will seriously affect the accuracy of frequency spectrum separation. This paper carries out a simulation study on the influence of noise in the process of frequency spectrum separation. The results show that although noise can cause distortion of low-frequency information in frequency spectrum separation results, it has little influence on high-frequency information. Therefore, a super-resolution image reconstruction method is proposed to effectively suppress the influence of noise. Both simulation and experimental results are shown the method can suppress the influence of noise without losing the details of super-resolution.
