摘 要:本文用空位自补偿理论来研究半导体氮化物的导电类型,确定了未掺杂的铝、镓、铟的氮化物都是n型,并认为这些氮化物是具有一定自补偿的双极性材料。
Abstract: The conductivity types of semiconductor nitrides have been investigated by using vacancy self-compensation theory. It is found that all undoped AlN, GaN and InN are expected to be n--type. It is also evaluated that these nitrides are ambipolar compounds, in spite of a partial self-compen- sation existing in them.
