Times Cited Count：7 Percentile：41.38(Physics, Condensed Matter)Carrier concentration and defects in n+/p InGaP irradiated with 100keV-protons (1E10, 5E12 /cm2) were studied.As a result of C-V measurements, the carrier removal rate was estimated to be 6.1E4 /cm2 which was extremely high as compared to 1MeV-electron irradiation case (0.93 /cm). H1 peak whose energy corresponds to Ev+0.90V was obtained from DLTS measurements. This suggests that carrier removal rate in proton-irradiated ones is much higher than that in electron-irradiated ones due to the generation of the defects (H1 peak) which act as majority carrier traps.

Femtosecond laser sintering is a promising technique for 2D/3D micro additive manufacturing. In this process, nanoparticles dispersed in binders were coated on substrates, and femtosecond laser pulses were subsequently focused and scanned to write patterns. We also applied this process to fabricating SiC microstructures using SiC nanoparticles of 
100 nm in diameter. In this study, we prepared a SiC nanoparticle ink including finer SiC nanoparticles with the diameter of ~18 nm. First, a SiC nanoparticle ink with the mixture of 100 nm and 18 nm in diameters was prepared. Then, patterning properties by femtosecond laser sintering were evaluated at various laser irradiation conditions. By comparing to the reference ink (SiC nanoparticles of 100 nm in diameter), the SiC nanoparticles with fine nanoparticles (18 nm) decreased the line width. In addition, the ablation width of in the center of the lines decreased by consisting fine particles. These results suggest that the fine nanoparticles increased the surface area in the inks, resulting that the large surface increased the consumption of the irradiated energy, and thermal conductivity of the ink decreased.
