An On-Chip Quad-Wavelength Pyroelectric Sensor for Spectroscopic Infrared Sensing
Thang Duy Dao, Satoshi Ishii, Anh Tung Doan +4
Merging photonic structures and optoelectronic sensors into a single chip may yield a sensor-on-chip spectroscopic device that can measure the spectrum of matters. In this work, we…
Unidirectional light transmission by two-layer nanostructures interacting via optical near-fields
M. Naruse, S. Ishii, J. -F. Motte +3
We experimentally demonstrate unidirectional light transmission through two-layer nanostructured materials considering that the horizontal-to-vertical-polarization conversion effic…
Inversion-induced orbital and exchange disorders in antiferromagnetic A-site spinel CoAl2O4
Takashi Naka, Hiroaki Mamiya, Kanji Takehana +6
The inversion and volume effects on magnetism in a spinel-type magnetically frustrated compound, CoAl2O4, and its gallium-substituted system, CoAl2-xGaxO4, were investigated. Magne…
Band engineering of ternary metal nitride system Ti1-x ZrxN for plasmonic applications
Mukesh Kumar, Satoshi Ishii, Naoto Umezawa +1
Chemical composition is the primary factor that determines the electronic band structure and thus also influences the optical properties of plasmonic ceramics including nitrides an…
Examining the performance of refractory conductive ceramics as plasmonic materials: a theoretical approach
Mukesh Kumar, Naoto Umezawa, Satoshi Ishii +1
The main aim of this study is to scrutinize promising plasmonic materials by understanding their electronic structure and correlating them to the optical properties of selected ref…
Multistage ordering and critical singularities in Co1-xZnxAl2O4 (0 < x < 1):Dilution and pressure effects in a magnetically frustrated system
Takashi Naka, Koichi Sato, Yoshitaka Matsushita +9
We report comprehensive studies of the crystallographic,magnetic, and thermal properties of a spinel-type magnetically frustrated compound, CoAl2O4, and a magnetically diluted syst…
