A new method to measure the depth of subsurface defects in additive manufacturing components is proposed based on the velocity dispersion analysis of Lamb waves by the wavelet-transform of laser ultrasound. Firstly, the mode-conversion from laser-gen

The heteroepitaxial β-Ga2O3 films were grown on the (0 0 0 1) sapphire substrates with various off-angles toward 〈1 1 2 - 0〉 by halide vapor phase epitaxy (HVPE). The effects of off-angled substrates on the surface morphologies and crystal quali
