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…
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…
