Weight … WebFor n-type it has been assumed that the number of k-type donors is the same as the number of h-type donors. Thus, the nitrogen donor level was set to the average value for all sites, =70 and =100 meV for 4H and 6H-SiC, respectively. The p-type results were calculated assuming the aluminum acceptor value =200 meV.
