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…
Superconductivity at 48 K of heavily hydrogen-doped SmFeAsO epitaxial films grown by topotactic chemical reaction using CaH2
Jumpei Matsumoto, Kota Hanzawa, Masato Sasase +4
High-critical-temperature (Tc) superconductivity at 48 K is reported for hydrogen-doped SmFeAsO epitaxial films on MgO single-crystal substrates. The key processes are pulsed laser…
Particulate Generation on Surface of Iron Selenide Films by Air Exposure
Hidenori Hiramatsu, Kota Hanzawa, Toshio Kamiya +1
Nanometer-sized particular structures are generated on the surfaces of FeSe epitaxial films directly after exposure to air; this phenomenon was studied in the current work because…
Insulator-like behavior coexisting with metallic electronic structure in strained FeSe thin films grown by molecular beam epitaxy
Kota Hanzawa, Yuta Yamaguchi, Yukiko Obata +4
This paper reports that ~10-nm-thick FeSe thin films exhibit insulator-like behavior in terms of the temperature dependence of their electrical resistivity even though bulk FeSe ha…
