Description
タ(spectrally matched phototransistor)と共に用いられてきた。
らの成長を容易にし、またそれらの所望の特性が得られる水素雰囲気下で成長させる。H2下でのこの成長は、図1の矢印25で示してある。次に、第二GaN層14、InGaN量子井戸12、第三GaN層15、及び第一AlGaN層21を、窒素雰囲気下で、好ましくは成長を停止させずに成長させる。最後に、第二AlGaN層22及び第四GaN層23を、好ましくは成長を停止させずに水素雰囲気下で成長させる。この方法では、水素雰囲気から窒素雰囲気への切り替えがドーピングされていないGaN層14で起こり、また窒素から水素へと戻す対応する切り替えは、ドーピングされていないAlGaN層21の後で起こるので、InGaN量子井戸12ならびに当該井戸に隣接している層は、成長を停止せずにすべて成長する。結晶成長技術、特にCVDエピタキシャル成長技術に精通している当業者には公知のように、連続成長ブロセスは、停止を含む成長プロセスに比べて、エピタキシャル層の間に著しく良好な界面を生成する傾向がある。この方法では、本発明にしたがうLEDの構造は、成長技術を向上させ、また連続成長技術はLEDの得られる特性を向上させる。
使用する場合、本発明のダイオードを用いて、赤色LED、緑色LED及び青色LEDを組込んでいるピクセル及びディスプレイの両方を提供することができる。
