First-Principles Study on Strain-Induced Modulation of Electronic Properties in Indium Phosphide.

Indium phosphide (InP) is widely utilized in the fields of electronics and photovoltaics due to its high electron mobility and high photoelectric conversion efficiency. Strain engineering has been extensively employed in semiconductor devices to adjust physical properties and enhance material performance. In the present work, the band structure and electronic effective mass of InP under different strains are investigated by ab initio calculations.

Molecular Dynamic Simulation of Primary Damage with Electronic Stopping in Indium Phosphide.

Indium phosphide (InP) is an excellent material used in space electronic devices due to its direct band gap, high electron mobility, and high radiation resistance. Displacement damage in InP, such as vacancies, interstitials, and clusters, induced by cosmic particles can lead to the serious degradation of InP devices. In this work, the analytical bond order potential of InP is modified with the short-range repulsive potential, and the hybrid potential is verified for its reliability to simulate the atomic cascade collisions.

First-principles investigation of positively charged and neutral oxygen vacancies in amorphous silica.

The structural parameters, electron localization functions, electron paramagnetic resonance (EPR) parameters, formation energies, and thermodynamic transition levels of various oxygen vacancy defects in amorphous silica are comprehensively and integrally investigated by using density functional theory. The trends of changes in the oxygen vacancy defect structure and electron localization induced by the increase in distance between defective silicon atoms are clearly identified. It is shown that the dimer configuration may be the potential structure of the Eδ' center.

Theoretical insights into volatile iodine adsorption onto COF-DL229.

COF-DL229 is one of the promising sorbents for the capture of volatile radioiodine due to its large adsorption capacity. However, the interaction mechanism between them remains unclear. In the present work, the adsorption of volatile iodine onto COF-DL229 was systematically investigated using periodic density functional theory and crystal orbital Hamilton population calculations.

[The evaluation of the treatment for the cavernous hemangioma and peripheral vascular disorders with copper needles].

Objective: The goal of this study was to evaluate the effect of different methods of treating for the cavernous hemangioma and peripheral vascular disorders with copper needles.

Methods: 21 cases were treated with copper needle retention only, 57 cases were treated with copper needle retention combined with a direct current of 6 - 9 V, both the inserted needles were kept in the site until the reaction was over, for about 10 to 20 days, 27 cases were treated with copper needle insertion combined with a direct current, and then the affection was ablated immediately.

Results: The early effective rate, the long-term effective rate, and the recurrence rate of the total cases were 94.
