Interband spectroscopy of Landau levels and magnetoexcitons in bulk black phosphorus
H. Okamura, S. Iguchi, T. Sasaki +3
Low-dimensional systems based on black phosphorus (BP) have recently attracted much interest. Since the crystal structure of BP consists of 2D layers with a strong in-plane anisotr…
Pressure suppression of the excitonic insulator state in Ta2NiSe5 observed by optical conductivity
H. Okamura, T. Mizokawa, K. Miki +9
The layered chalcogenide Ta2NiSe5 has recently attracted much interest as a strong candidate for the long sought excitonic insulator (EI). Since the physical properties of an EI ar…
Photogenerated Carriers in SrTiO3 Probed by Mid-Infrared Absorption
H. Okamura, M. Matsubara, K. Tanaka +6
Infrared absorption spectra of SrTiO have been measured under above-band-gap photoexcitations to study the properties of photogenerated carriers, which should play important ro…
Photoinduced spin crossover in Fe-picolylamine complex: A farinfrared study on single crystals
H. Okamura, M. Matsubara, T. Nanba +7
Far-infrared spectroscopy has been performed on [Fe(2-picolylamine)3]Cl2EtOH (Fe-pic) single crystals, to probe changes in the molecular vibrations upon the photoinduced and temper…
Infrared study of spin crossover Fe-picolylamine complex
Hidekzu Okamura, Masato Matsubara, Takeshi Tayagaki +5
Infrared (IR) absorption spectroscopy has been used to probe the evolution of microscopic vibrational states upon the temperature- and photo-induced spin crossovers in [Fe(2-picoly…
