  Iterative peak-fitting of frequency-domain data via deep convolution neural networks

  Seong-Heum Park, Hyeongseon Park, Hyunbok Lee et al.

  We combine deep convolution neural networks and conventional global optimization techniques to analyze x-ray photoemission data. By employing the most advanced form of convolution neural network architecture, we could iteratively subtract peak features from synthetic and actual photoemission spectra...

  Synthesis of Ni-based fluoroperovskites by solvent-free mechanochemical reaction

  Jin San Choi, Muhammad Sheeraz, Fazli Akram et al.

  Ni-based fluoroperovskite ANiF3 (A = Na, K, and Ag) is a promising candidate of emerging materials due to potential applications to functional devices as well as large variety of novel physical phenomena. Despite the tremendous interest, synthesis of the fluoroperovskites is challenging owing to the...

  Effects of Oxygen Adsorption on Morphological Evolution of Epitaxial Ag Island Films Grown on Si

  Jongpil Ye, Dongchul Lee, Yongsik Jin

  In this paper, we investigate the effect of annealing gas compositions on the morphological evolution of heteroepitaxial silver island films grown on silicon substrates. We show that the presence of oxygen during thermal annealing leads to the formation of more isotropic silver islands with enhanced...

  Effects of the Intercalant and the Temperature in Hybrid-MoS₂ Nanodots Fabrication and Their Photoluminescence Enhancement

  Adila Rani, Eun-Young Kim, Da Som Song et al.

  (a) Synthesis of different sizes of hybrid MoS2 NDTs using hydrothermal method by the incorporation of KNa-tartrate as an intercalant. (b) Mechanism of the hybrid NDTs showing dissociation of intercalant into carbon nanodots and edges of MoS2 is broken into small sizes; resulting carbon and oxygen f...

  Electrical and Chemical Sensing Properties of a Printed Indium-Tin-Oxide Film for the Detection of Hazardous and Noxious Substances

  Jun Seck Choi, Dong Wan Ko, Jun Young Seo et al.

  We have investigated the feasibility of the printed ITO films as a chemical sensor. ITO films were printed on a PET substrate by using an ITO (Sn ~10%) power which has an average particle size of 45nm. Superior chemical sensing performance of ITO films was observed in compared with the results of sp...

  Direct Evidence of Simultaneous Reversal of Ferrimagnetically Coupled Sm 4f and Mn 3d Angular Momenta in SmMnO₃

  J.-S. Jung, T. Nakamura, Y. Wakabayashi et al.

  A N?el N-type ferrimagnet, SmMnO3, exhibits a striking magnetocapacitive effect around the compensation temperature. To clarify the origin of the magnetocapacitive effect, the magnetic states of the Sm 4f and the Mn 3d moments in SmMnO3 were investigated by means of X-ray magnetic circular dichroism...

  Bend-Insensitive Simultaneous Measurement of Strain and Temperature based on Cascaded Long-Period Fiber Gratings Inscribed on a Polarization-Maintaining Photonic Crystal Fiber

  Do Kyung Kim, Seul-Lee Lee, Sungwook Choi et al.

  (a) Schematic diagram of the fabrication setup for cascaded long-period fiber gratings (LPFGs) on polarization-maintaining photonic crystal fiber (PMPCF), (b) side-view image of the fabricated grating, and (c) its polarization-dependent in- fiber Mach-Zehnder interference spectra measured for orthog...
