Metamaterials exhibiting exotic optical properties have played a significant role over the years in guiding the concept of invisibility cloaking from the realm of being fiction to reality. However, due to the difficulties in fabricating the 3D cloaking devices and lack of exotic pla... |

Tan, Thomas Caiwei; Srivastava, Yogesh Kumar; Manjappa, Manukumara; Plum, Eric; Singh, Ranjan, 2020, "Replication Data for: Lattice induced strong coupling and line narrowing of split resonances in metamaterials", https://doi.org/10.21979/N9/UMA5GK, DR-NTU (Data), V2, UNF:6:PJXrGIhBxyvUWgNaWWPejg== [fileUNF]
Strongly coupled metamaterial resonances typically undergo mode-splitting by which there is an exchange of energy between matter excitations and photons. Here, we report a strong coupling of the lattice mode with the structural eigen resonances of a split-ring metamaterial associ... |

Fano resonances in metamaterials are known for their high quality (Q) factor and high sensitivity to external perturbations, which makes them attractive for sensors, lasers, non-linear and slow light devices. However, Fano resonances with higher Q factors obtained through structu... |

Solution-processed metal halide perovskites (MHPs) have demonstrated great advances on achieving high-performance photodetectors. However, the intrinsic material instability and the toxicity of lead still hinder the practical applications of MHPs-based photodetectors. In this wor... |

Shao, Feng; Qin, Peng; Wang, Dong; Zhang, Guoqing; Wu, Bo; He, Jianqiao; Peng, Wei; Sum, Tze Chien; Wang, Deliang; Huang, Fuqiang, 2020, "Replication Data for: Enhanced Photovoltaic Performance and Thermal Stability of CH3NH3PbI3 Perovskite through Lattice Symmetrization", https://doi.org/10.21979/N9/WTJDXM, DR-NTU (Data), V1
The organic–inorganic lead halide perovskites are attractive materials for photovoltaic application. The most widely studied perovskites based on methyl ammonium organic cation are less likely to form an ideal high-symmetry configuration at room temperature, leading to the appear... |
