Theoretical and Experimental Investigation into the Branched Flow Phenomenon of Light
Han Lin, Xiaoyue Ma, Kefan Wang
Branched flow can be observed when a laser beam is coupled into a soap film. This research theoretically explored the phenomenon through analogy between light wave and particles in…
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…
Influences of Si sheet doping densities on the morphological, conductive and optical characteristics of InAs/GaAs quantum dots
Ke-Fan Wang, X. G. Yang, Y. X. Gu +3
The influences of Si sheet doping levels on the properties of InAs/GaAs quantum dots (QDs) are investigated by atomic force microscopy (AFM) and photoluminescence (PL). AFM measure…
