  • Abstract
    The mobility and carrier concentration carrier depth profiles have been measured for a GaN epilayer grown by plasma-assisted MBE. The results show that the apparent carrier concentration increases at the interface whilst the apparent mobility decreases. A two-layer model can be used to explain this behaviour
