The crystal structure, surface morphology, chemical state and optical properties of Al-doped ZnO films grown at different sputtering powers are studied. Results indicated that compressive stress related to defects exists in all the samples measured by X-ray diffraction. Blue-green emission mechanisms a blue-shift were explored based on sites. peak 458 nm comes from electron transition interstitial Zn top valence band conduction misplaced oxygen defects. 490 vacancies or O complex defect...
We have performed the first-principles calculations on structural, electronic, and magnetic properties of 3d transition-metal™ (Cr, Mn, Fe, Co, Ni) atoms doped 2D GaN nanosheet. The results show that TM atom substituting one Ga leads to a structural reconstruction around impurity compared pristine doping can induce moments, which are mainly located its nearest-neighbor N atoms. It is found Mn- Ni-doped nanosheet with 100% spin polarization characters seem be good candidates for spintronic...
Finding ideal perovskite oxides for water splitting is challenging due to their vast compositional space.In this study, the TPOT machine learning approach was utilized predict photocatalytic properties of 5329 ABO3-type based on 14 features. Regression and classification models were built band edge locations gap types. After optimization, model error decreased by 42.4% . Eventually, 57 promising candidates identified sorted according characteristics assist experimental synthesis, suggesting...
The first principles method is utilized to study the adsorption properties of CO2, NO2 and SO2 on pristine modified BP. results indicate that doping defects can effectively regulate electronic sensing performance BP systems. Eads decrease after introduction defects, indicating improve stability shows non-magnetic semiconductor band gap 0.89 eV, defective exhibits nonmagnetic metal properties. After adsorbing gas molecules, systems exhibit semiconductor, ferromagnetic metallic, magnetic...
Atomically precise Au25 superatoms with electron-deficient Au12 shells and electron-rich Au13 cores immobilized on the surface of CeO2 nanorods achieved novel catalytic activity for styrene oxidation.
We study the electronic and magnetic structures of quasi-one-dimensional interfaces along zigzag direction in two-dimensional GaN/SiC heterostructures using first-principles calculations. Four representative with six inequivalent are discussed detail. Our results indicate that a bulk electric field will develop only when both feature no gap states total net charge at opposite sign. All geometries studied exhibit an intriguing conductor character, which three show finite nonzero moment....
