To develop high-performance semiconductor devices, it is critical to study the relationship between stress and phonon frequency shifts. We used micro-Raman spectroscopy on a β-Ga2O3(001) wafer to better understand the relationship. We applied tensil

Wurtzite AlN films with high Fe concentrations were deposited on Si(100) substrates using radio-frequency sputtering, and the growth process was investigated. X-Ray diffraction (XRD) analysis with parallel incident X-rays showed that a thick film (

We reported our observation results on the etch pit shapes on β-Ga2O3 (001) wafers using a scanning electron microscope (SEM) and an atomic force microscope (AFM) in a previous study. However, it was difficult to detect the internal crystal defects

Stacking faults (SFs) in 4H-SiC epitaxial wafers were inspected by using a mirror projection electron microscope (MPJ) [1, 2]. Dark and bright line contrasts of SFs in MPJ images represent surface morphology and crystal defects located in the epitaxi

Two types of carrot defects with and without a shallow pit were found by mirror projection electron microscopy (MPJ) inspection in 4H-SiC epi wafer. Surface morphology and cross-sectional structure of prismatic stacking faults (PSFs) were investigate

In order to understand the crystal defects of beta-gallium oxide (β-Ga2O3) in more detail, we classified the crystal defects of a 2-inch substrate of β-Ga2O3 (001) single crystal. As a result of observing the etch pits formed by molten alkali etchi

The defect structure of Mg implanted GaN substrate was evaluated by TEM observations, AFM surface observations and Raman scattering spectroscopic analysis. Mg ions were implanted at room temperature (RT) and 500 °C. TEM results showed that the defec
