Thermoelectric response across the semiconductor-semimetal transition in black phosphorus
Yuna Nakajima, Yuichi Akahama, Yo Machida
In spite of intensive studies on thermoelectricity in metals, little is known about thermoelectric response in semiconductors at low temperature. An even more fascinating and unans…
Pressure induced evolution of band structure in black phosphorus studied by P-NMR
T. Fujii, Y. Nakai, Y. Akahama +2
Two-dimensional layered semiconductor black phosphorus (BP), a promising pressure induced Dirac system as predicted by band structure calculations, has been studied by P-nuc…
Double carrier transport in electron doped region in black phosphorus FET
Kohei Hirose, Toshihito Osada, Kazuhito Uchida +4
The double carrier transport has been observed in thin film black phosphorus (BP) field effect transistor (FET) devices in highly electron doped region. BP thin films with typical…
Prolonged photo-carriers generated in a massive-and-anisotropic Dirac material
Munisa Nurmamat, Yukiaki Ishida, Ryohei Yori +8
Transient electron-hole pairs generated in semiconductors can exhibit unconventional excitonic condensation. Anisotropy in the carrier mass is considered as the key to elongate the…
Observation of Poiseuille Flow of Phonons in Black Phosphorus
Yo Machida, Alaska Subedi, Kazuto Akiba +5
The travel of heat in insulators is commonly pictured as a flow of phonons scattered along their individual trajectory. In rare circumstances, momentum-conserving collision events…
Two-carrier analyses of the transport properties of black phosphorus under pressure
Kazuto Akiba, Atsushi Miyake, Yuichi Akahama +3
We report on the electronic transport properties of black phosphorus and analyze them using a two-carrier model in a wide range of pressure up to 2.5 GPa. In semiconducting state a…
Anomalous Quantum Transport Properties in Semimetallic Black Phosphorus
Kazuto Akiba, Astushi Miyake, Yuichi Akahama +5
Magnetoresistance in single crystals of black phosphorus is studied at ambient and hydrostatic pressures. In the semiconducting states at pressures below 0.71 GPa, the magnetoresis…
