Kosuke Shimano; Shunya Sakane; Takehiro Ota; Kenichiro Takakura; Motoharu Imai; Haruhiko Udono, Corresponding, We thoroughly investigated the Raman peaks of Sb- or Bi-doped Mg2Si single crystals grown by the vertical Bridgman techniques and clarified the relationship between the Raman peak shift and lattice strain using first-principles calculations. Rietveld analysis of powder x-ray diffraction revealed that the lattice constant increased monotonically with Sb and Bi doping amounts. Raman spectroscopy demonstrated that the F2g mode of Mg2Si (near 258 cm−1) shifted to lower wavenumbers with increasing doping amounts. This peak shift was mainly attributed to the lattice strain, which was revealed by the first-principles calculations. These findings provide the usefulness of Raman spectroscopy for Mg2Si substrates., AIP Publishing

Akito Ayukawa; Nozomu Kiridoshi; Wakaba Yamamoto; Akira Yasuhara; Haruhiko Udono; Shunya Sakane, Abstract
High-quality epitaxial Mg3Sb2 thin films are promising thermoelectric materials to enable practical applications of compact and environmentally friendly thermoelectric conversion at room temperature. In this study, high-quality single-crystal Mg3Sb2 with high c-plane orientation were epitaxially grown directly on annealed c-Al2O3 substrates without passive layers. These thin films exhibited three times higher thermoelectric power factor than ever reported values due to high carrier mobility. The ultra-smooth surface of the annealed c-Al2O3 substrate facilitated the formation of high-quality Mg3Sb2 thin films without passive layers or polycrystalline interfaces that could be carrier scatters., IOP Publishing

Journal of Materials Science, 10 May 2023, [Reviewed] - 〔Major achievements〕Study of deep levels in the Mg2Si grown by vertical Bridgman method
Kouki Fukushim; Naoki Mizunuma; Tatsuya Uematsu; Kyoko Shimizu; Takehiro Ota; Isao Tsunoda; Haruhiko UDONO and Kenichiro Takakura, Abstract
The electrical characteristics of a Mg2Si p–n junction diode was investigated. The n-Mg2Si substrate was grown by using the vertical-Bridgeman method. A p–n junction was fabricated by the thermal diffusion of Ag as an acceptor. The reverse current of the Au/Ag electrode diode was larger than that of the Ag electrode diode. The trap levels in the n-Mg2Si bulk were investigated using deep-level transient spectroscopy. The magnitude of DLTS signal of E1 with the Au/Ag electrode diode was larger than that for the signals at the other trap levels. The E1 level corresponds to an Au-related trap that diffuses via thermal annealing during the alloying process. The open-circuit-voltage-decay study suggests the existence of a minority-carrier trap in n-Mg2Si. The minority-carrier lifetime was shorter for Au/Ag electrode diodes. Therefore, Au may be involved in the formation of minority-carrier traps, as well as in the formation of majority-carrier traps., IOP Publishing

Jpn. J. Appl. Phys., 28 Nov. 2022, [Reviewed] - 〔Major achievements〕Effects of dopant type and concentration on surface recombination velocity in hydrogen-terminated silicon
Nobue Araki; Haruhiko Udono, Abstract
Isolating the effects of the type and concentration of the dopant in lightly doped regions in the reaction between hydrogen-terminated silicon surface and atmospheric impurities in air is very difficult. However, changes in the surface recombination sites can be analyzed accurately through recombination lifetime measurements performed using the microwave photoconductive decay method. Thus, we investigated variations in the effective recombination lifetime in hydrogen-terminated silicon surfaces over time in air for different dopant types and concentrations. For both p-type and n-type silicon wafers, surface recombination velocity, S, increased with decreasing resistivity, namely, increasing dopant concentration. The time-dependent variations of the S for the p-type wafers decreased, and those for the n-type wafers increased with decreasing resistivity. Thus, it was shown that the time-dependent variation of the S depends on the type and concentration of the dopant used., IOP Publishing

Journal of Physics and Chemistry of Solids, Feb. 2013, [Reviewed] - Thermoelectric properties of Na-doped Mg2Si0.25Sn0.75
S. Tada; Y. Isoda; H. Udono; H. Fujiu; S. Kumagai and Y. Shinohara, We have investigated the thermoelectric properties of Na-doped Mg2Si0.25Sn0.75 solid solutions prepared by liquid-solid reaction and hot-pressing methods. Na doping was carried out by mixing sodium acetate (CH3COONa) into the starting materials Mg (nominal purity: 99.9 %), Sn (99.999 %) granules, and Si powder (99.9999 %). The Na-doped samples had p-type conductivity with positive signs of Seebeck and Hall coefficients. Furthermore, hole concentrations increased rapidly with an increase in the amount of Na doping. These results revealed that the Na atoms acted as acceptors in Mg2Si0.25Sn0.75. The Seebeck coefficient of Na-doped samples showed positive values between 300 and 750 K. A maximum power factor of 0.88 × 10-3 WmK-2 was observed for the Mg2Na0.020Si0.25Sn0.75 sample at 500 K. The dimensionless figure of merit ZT reached 0.17 at 450 K for all Na-doped samples., The Materials Research Society of Japan

H. Udono and I. Kikuma, We have succeeded in growing large-sized β-FeSi2 crystal (10 mm in diameter and 0.3-0.5 mm in thickness) by a temperature gradient solution growth method using a carbon plate. The grown crystals had large-sized grain boundaries with an area of about (1-2)× (1-4) mm2. Optical absorption measurements were performed at room temperature on single crystalline specimens prepared from the grown crystals. The absorption spectra suggest that β-FeSi2 has an indirect band-gap structure with a gap energy of approximately 0.75 eV., The Japan Society of Applied Physics
