Plasmonic- and Electronic-Enhancement-Free Coherent Raman Detection of Ångström-Scale Molecular Layers at Metal Interfaces
Toshiki Sugimoto, Tomoaki Ichii, Tsuneto Kanai +5
Coherent Raman scattering provides highly sensitive vibrational analysis through nonlinear light-matter interactions. However, its application to metal interfaces has remained chal…
Study of detailed balance between excitons and free carriers in pristine diamond using terahertz spectroscopy
T. Ichii, Y. Hazama, N. Naka +1
A fundamental understanding of the photoexcited carrier system in diamond is crucial to facilitate its application in photonic and electronic devices. Here, we studied the detailed…
Observation of exotic water in hydrophilic nanospace of porous coordination polymers
Tomoaki Ichii, Takashi Arikawa, Kenichiro Omoto +4
The fundamental understanding of water confined in porous coordination polymers (PCPs) is significantly important not only for their applications such as gas storage and separation…
Lattice phonon modes of the spin crossover crystal [Fe(phen)2(NCS)2] studied by THz, IR, Raman spectroscopies and DFT calculations
Eric Collet, Giovanni Azzolina, Tomoaki Ichii +9
[Fe(phen)2(NCS)2] is a prototype transition metal complex material, which undergoes a phase transition between low-spin (LS) and high-spin (HS) phases, induced by temperature, pres…
