WebMay 31, 2024 · Near-interface traps are more critical compared to bulk traps for the mobility of SiC MOSFETs. The oxidation process can also cause the injection of carbon into SiC substrate. This injected carbon can exist in different forms such as carbon interstitials ( C i ) and carbon di-interstitials ( C i ) 2 to further degrade the FET channel mobility [ 4 – 6 , 24 ]. WebMay 15, 2024 · DFT calculations of hole trapping in crystalline phase monoclinic HfO 2 and corundum Al 2 O 3 demonstrate that holes can trap predominantly on one oxygen site with trapping energies of around 0.2 eV. In rutile TiO 2 no hole trapping was found, but in anatase the calculations [ 116 ] predict the hole trapping with the trapping energy of ∼1.1 eV. WebQuasi Steady State Photo Conductance measurements shows a promising effective carrier lifetime of 420 μs, surface recombination velocity of 22 cm/s and a low interface trap density (D(it)) of 4 x 10(11) states/cm2/eV after annealing.
