Prediction of Born effective charges using neural network to study ion migration under electric fields: applications to crystalline and amorphous Li3PO4
Autor: Koji Shimizu, Ryuji Otsuka, Masahiro Hara, Emi Minamitani, Satoshi Watanabe
Publikováno v: Science and Technology of Advanced Materials: Methods, Vol 3, Iss 1 (2023)
Understanding ionic behaviour under external electric fields is crucial to develop electronic and energy-related devices using ion transport. In this study, we propose a neural network (NN) model to predict the Born effective charges of ions along an

Impacts of post-deposition annealing on hole trap generation at SiO2/p-type GaN MOS interfaces
Autor: Kazuki Tomigahara, Masahiro Hara, Mikito Nozaki, Takuma Kobayashi, Heiji Watanabe
Publikováno v: Applied Physics Express, Vol 17, Iss 8, p 081002 (2024)
In this study, impacts of post-deposition annealing (PDA) on hole trap generation at SiO _2 /p-GaN MOS interfaces are investigated. While the surface potential is strongly pinned due to severe hole trapping after 800 °C PDA, successful hole accumula

Risk factors for malnutrition among school-aged children: a cross-sectional study in rural Madagascar
Autor: Hirotsugu Aiga, Kanae Abe, Vonjy Nirina Andrianome, Emmanuel Randriamampionona, Angèle Razafitompo Razafinombana, Toshiyasu Murai, Masahiro Hara
Publikováno v: BMC Public Health, Vol 19, Iss 1, Pp 1-13 (2019)
Abstract Background For over 20 years, Madagascar has been challenged by continued high prevalence of stunting, underweight and wasting among children under 5 years of age. Yet, nutritional status of post-under-five age group has never been assessed

Impact of the split-off band on the tunneling current at metal/heavily-doped p-type SiC Schottky interfaces
Autor: Takeaki Kitawaki, Masahiro Hara, Hajime Tanaka, Mitsuaki Kaneko, Tsunenobu Kimoto
Publikováno v: Applied Physics Express. 16:031005
Ni/p-type SiC Schottky barrier diodes with various acceptor densities (N A = 5 × 1015 to 3 × 1019 cm−3) are fabricated and the measured current–voltage characteristics are analyzed by numerical calculation of tunneling current. The tunneling cu

Enhanced tunneling current and low contact resistivity at Mg contacts on heavily phosphorus-ion-implanted SiC
Autor: Masahiro Hara, Mitsuaki Kaneko, Tsunenobu Kimoto
Publikováno v: Applied Physics Express. 16:021003
Mg contacts are formed on P+-implanted SiC (1 × 1017–8 × 1019 cm−3) and their current–voltage characteristics and contact resistivity (ρ c) are analyzed. The current density through the contacts on the ion-implanted SiC is several orders of
