Abstract：

InGaN/GaN　MQWs　structures　were　grown　by　MOCVD.　The　effects　of　the　growth　interruption　time　on　the　optical　and　structural　properties　of　InGaN/GaN　MQWs　were　investigated.　The　growth　interruption　can　improve　the　interface　quality,　increase　the　intensity　of　photoluminescence　(PL)　and　electroluminescence　(EL);　but　if　the　interruption　time　was　too　long,　the　well　thickness　and　the　average　in　composition　of　MQWs　decreased,　and　the　EL　intensity　also　decreased　due　to　poor　interface　quality　and　impurity　derived　by　growth　interruption.
