Tellurium trioxide as an n-type wide-gap semiconductor with ultrahigh work functions from first principles
Tianwei Wang, Teruya Nagafuji, Kota Hanzawa +2
The exploration of next-generation wide-gap semiconductors with extreme work functions is highly desirable for the continued advancement of electronic and optoelectronic devices. B…
Nonreciprocal charge transport in an iron-based superconductor with broken inversion symmetry engineered by a hydrogen-concentration gradient
Takayuki Nagai, Yukito Nishio, Jumpei Matsumoto +4
The breaking of spatial inversion symmetry in condensed matter gives rise to intriguing physical properties, such as ferroelectricity, piezoelectricity, spin-momentum locking, and…
Fully automated spectroscopic ellipsometry analyses of crystalline-phase semiconductors based on a new algorithm
Sara Maeda, Kohei Oiwake, Yukinori Nishigaki +8
One significant drawback of a spectroscopic ellipsometry (SE) technique is its time-consuming and often complicated analysis procedure necessary to assess the optical functions of…
Heteroepitaxial Thin-Film Growth of a Ternary Nitride Semiconductor CaZn2N2
Masatake Tsuji, Kota Hanzawa, Hiroyuki Kinjo +2
Zinc-based nitride CaZn2N2 films grown by molecular beam epitaxy (MBE) with a plasma-assisted active nitrogen-radical source are promising candidates of next-generation semiconduct…
Stabilization and heteroepitaxial growth of metastable tetragonal FeS thin films by pulsed laser deposition
Kota Hanzawa, Masato Sasase, Hidenori Hiramatsu +1
Pulsed laser deposition, a non-equilibrium thin-film growth technique, was used to stabilize metastable tetragonal iron sulfide (FeS), the bulk state of which is known as a superco…
