Theoretical insight into the interaction of O2 and H2O molecules with the perfect and the defective InSe monolayers
Dongwei Ma, Tingxian Li, Chaozheng He +4
By using first-principles calculation, the interaction of O2 and H2O molecules with the pristine and the defective InSe monolayers is studied. It is predicted that the single Se an…
Half-filled intermediate bands Si material formed by energetically metastable interstitial sulfur atom
Ke-Fan Wang, Mingguo Liu, Yaping Ma +3
Hyperdoped metastable sulfur atoms endow crystalline silicon with a strong sub-bandgap light absorption. In order to explore such metastable states, we develop a new high-throughpu…
Possible atomic structures for the sub-bandgap absorption of chalcogen hyperdoped silicon
Ke-Fan Wang, Hezhu Shao, Kong Liu +3
Single-crystal silicon wafers were hyperdoped respectively by sulfur, selenium, and tellurium element using ion implantation and nanosecond laser melting. The hyperdoping of such c…
Optical and electrical properties of textured sulfur hyperdoped silicon: a thermal annealing study
Ke-Fan Wang, Shengchun Qu, Yuanxu Wang +1
When the sulfur element is hyperdoped into crystalline silicon to a supersaturated density of 1020 cm-3, it can enhance the sub-bandgap light absorption of silicon from 0 to 70%, w…
The reltation between the electronic structure and thermoelectric transport properties for Zintl compounds M2Zn5As4 (M=K, Rb)
Gui Yang, jueming Yang, Yuli Yan +1
The electronic structure and thermoelectric properties of are studied by the first principles and the semiclassical BoltzTrap theory.
First principle study on electronic structure of ferroelectric PbFe0.5Nb0.5O3
Yuan Xu Wang, C L Wang, M L Zhao +1
The full potential linearized augmented plane wave (FLAPW) method was used to study the crystal structure and electronic structure properties of PbFe0.5Nb0.5O3 (PFN). The optimized…
