Abstract This study systematically compared the material and electrical properties of Al2O3 films deposited on n-type 4H-SiC substrates using thermal plasma-enhanced atomic layer deposition (ALD), referred to as PE-Al2O3 T-Al2O3, respectively. Atomic force microscopy data indicates that roughness SiC by both ALD procedures is low. X-ray photoelectron spectroscopy analysis suggests proportion hydroxides T-Al2O3 surfaces greater than PE-Al2O3. Based O 1s energy loss spectra fitting absorption...
The input-parallel output-parallel (IPOP) dc–dc converters are suitable for low-voltage and high-current applications, especially using high-frequency isolation instead of traditional line-frequency transformer ac–dc in dc distribution.
