Native defects and their complexes in spinel LiGa5O8: the puzzle of p-type doping

Klichchupong Dabsamut, Kaito Takahashi, Walter R. L. Lambrecht

Recently, LiGa${}_5$O${}_8$ was identified as a cubic spinel type ultra-wide-band-gap semiconductor with a gap of about 5.36 eV and reported to be unintentionally p-type. Here we prese…
