However , it is not easy to incorporate large n concentration in gap due to the large differences in lattice structure ( gan belongs to wurtzite structure while gap zinc blende structure ) and in lattice constant ( ~ 20 % ) between gan and gap , which will lead to an extremely large miscibility gap 然而要在gap中实现高浓度的掺氮并不容易。这主要是由于gap和gan之间较大的物理特性的差异,特别是晶格结构和晶格常数的差异,使得gap和gan存在较大的可混溶性间隙,从而难以生长高质量的高掺氮的gap材料。
