Atomic structure, electronic structure and optical absorption of inorganic perovskite compounds Cs2SnI6-nXn (X=F, Cl, Br; n= 0~6): A first-principles study
Wang Xuan, Tang Yehua, Nairui Xiao +1
As a possible alternative to organic-inorganic hybrid perovskite halide, inorganic Cs2SnI6 has drawn more and more research attention recently. In order to find more Cs2SnI6 deriva…
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…
