Abstract(in English) | To realize SiC n-channel insulated gate bipolar transistors (IGBTs) with very low on-resistance, it is required to reduce the resistance in thick p+-type SiC substrate that is a collector of n-channel IGBTs and to obtain high quality crystal. It is reported that codoping of Al and N in heavily Al-doped p-type 4H-SiC can form high quality epilayers. In this study, electrical properties of Al-N codoped p-type 4H-SiC epilayers are investigated. It is found that the codoping of N makes nearest-neighbor hopping conduction dominant at temperatures higher in the singly-doped samples. |
