| 1 | Accurate inverse design of Fabry–Perot-cavity-based color filters far beyond sRGB via a bidirectional artificial neural network显示文摘Structural color based on Fabry–Perot(F-P) cavity enables a wide color gamut with high resolution at submicroscopic scale by varying its geometrical parameters. The ability to design such parameters that can accurately display the desired color is therefore crucial to the manufacturing of F-P cavities for practical applications.This work reports the first inverse design of F-P cavity structure using deep learning through a bidirectional artificial neural network. It enables the production of a significantly wider coverage of color space that is over 215% of sRGB with extremely high accuracy, represented by an average ΔE_(2000) value below 1.2. The superior performance of this structural color-based neural network is directly ascribed to the definition of loss function in the uniform CIE 1976-Lab color space. Over 100,000 times improvement in the design efficiency has been demonstrated by comparing the neural network to the metaheuristic optimization technique using an evolutionary algorithm when designing the famous painting of 'Haystacks, end of Summer' by Claude Monet. Our results demonstrate that, with the correct selection of loss function, deep learning can be very powerful to achieve extremely accurate design of nanostructured color filters with very high efficiency. | PENG DAI YASI WANG YUEQIANG HU C.H.DE GROOT OTTO MUSKENS HUIGAO DUAN RUOMENG HUANG | 2021 | Photonics Research2021，9，5： | 2 |
| 2 | Two-dimensional Molecular Phase Transition of Alkylated-TDPB on Au(111)and Cu(111)Surfaces显示文摘The derivatives of aromatic cores bearing alkyl chains with different lengths are of potential interest in on-surface chemistry,and thus have been widely investigated both at liquid-solid interfaces and in vacuum.Here,we report on the structural evaluation of self-assembled 1,3.5-tri(4-dodecvlphenyl)benzene(TDPB)molecules with in creased molecular coverages on both Au(111)and Cu(111)surfaces.As observed on Au(111).thombic and herring bone structures emerge successively depending on surface coverage.In the case of Cu(111),the same process of phase conversion is also observed,but with two distinct structures.In comparison,the self-assembled structures on Au(111)surface are packed more densely than that on Cu(111)surface under the same preparation conditions.This may fundamentally result from the higher adsorption energy of TDPB molecules on Cu(111),restricting their adjustment to optimize a thermodvnamically favorable molecular packing. | ZHANG Junjie WANG Can DUAN Ruomeng PENG Chencheng YANG Biao CAO Nan ZHANG Haiming CHI Lifcng | 2020 | Chemical Research in Chinese Universities2020，36，4： | 0 |
