A Large-scale integration (LSI) has been improved by scaling contraction. Strained Si has been proposed as a higher carrier mobility than usual. We have evaluated the strained SiGe wafer by LTEM, which is a method of analyzing to detect THz waves generated by fs laser irradiated into the sample.
Phosphorpus-doped ZnO nanowires were synthesized by our newly developed nanoparticle-assisted pulsed-laser deposition (NAPLD) technique under various growth conditions. This NAPLD technique, which does not require a catalyst for crystal growth, is expected to synthesize high-quality nanostructured ZnO crystals. The luminescence properties were investigated by a photoluminescence (PL) spectroscopy,...
Transmission spectra of thin films of niobium nitride grown on a magnesium oxide substrate were measured by terahertz time-domain spectroscopy under several temperature conditions. Clear changes in the transparent terahertz waveform and transmission spectra of under / above a phase transition temperature were observed.
A planar-waveguide quasi-phase matched second-harmonic generation device, which consists of a Y-cut periodically poled MgO-doped LiNbO3 core and SiO2 claddings, provides 1-W green light with 30-% conversion efficiency at room temperature.
