- Effects of Interlayer Coupling on Hot Carrier Dynamics in Graphene-Derived van der Waals Heterostructures
Prineha Narang, Litao Zhao, Steven Claybrook and Ravishankar Sundararaman
Version of Record online: 24 MAR 2017 | DOI: 10.1002/adom.201600914
Hot carrier life times in graphene-based heterostructures exceed those in noble metals such as silver by two orders of magnitude for carriers close to the Fermi level. Carrier lifetimes decrease more rapidly with energy in these materials due to optical-phonon scattering and fall below those in silver 0.5 eV away from the Fermi level.
- Impact of White Light Illumination on the Electronic and Chemical Structures of Mixed Halide and Single Crystal Perovskites
Feng-Shuo Zu, Patrick Amsalem, Ingo Salzmann, Rong-Bin Wang, Maryline Ralaiarisoa, Stefan Kowarik, Steffen Duhm and Norbert Koch
Version of Record online: 24 MAR 2017 | DOI: 10.1002/adom.201700139
The electronic and chemical properties of perovskites are significantly affected upon white light illumination. Trap states, mainly consisting of elemental lead, pin the Fermi level at the surface of mixed halide and single crystal perovskites, giving rise to the surface n-type behavior. Concomitantly, iodine deficiency and the emergence of PbI2 are also observed.
- Reversible Tuning of Visible Wavelength Surface Lattice Resonances in Self-Assembled Hybrid Monolayers
Kirsten Volk, Joseph P. S. Fitzgerald, Pia Ruckdeschel, Markus Retsch, Tobias A. F. König and Matthias Karg
Version of Record online: 22 MAR 2017 | DOI: 10.1002/adom.201600971
Dynamically tunable surface lattice resonances in self-assembled particle arrays are demonstrated. Hexagonally ordered monolayers of wet-chemically synthesized hybrid core–shell particles with silver nanoparticle cores enable coupling between plasmonic and diffractive modes. A swellable, temperature-responsive polymer coating allows dynamic and fully reversible modulation of the surface lattice resonance position.
- High-Order Nonlinear Optical Properties Generated by Different Electron Transition Processes of NiO Nanosheets and Applications to Ultrafast Lasers
Bin Sun, Yuxia Zhang, Rui Zhang, Haohai Yu, Guowei Zhou, Huaijin Zhang and Jiyang Wang
Version of Record online: 21 MAR 2017 | DOI: 10.1002/adom.201600937
Multifunctional photonics properties of NiO nanosheets as strongly electron correlated material are endowed by manipulation of intraband and interband electron transition processes, including saturable absorption, optical limiting, and three-photon absorption and emission. Based on saturable absorption, a favorable broadband NiO saturable absorber is applied in the ultrafast mode-locked lasers at the wavelength of 1.06 and 1.34 µm.
- Water-Resonator-Based Metasurface: An Ultrabroadband and Near-Unity Absorption

Version of Record online: 21 MAR 2017 | DOI: 10.1002/adom.201601103
A water-resonator-based metasurface is demonstrated for near-unity and ultrabroadband absorption. The bandwidth reaches 78.9% and the angular tolerance is 45°. It is a significant milestone for tunable metasurfaces and absorption materials, which has potential applications in eliminating wall reflection in anechoic chambers, antiradar detection, and stealth technology, etc.
