Abstract
Description
歪=|ε|=|(ain−planーabulk)|/abulk
この式は前記格子定数を参照し、従ってウルツ鉱型層構造c−平面での歪を定義するけれども、ウルツ鉱型層構造の他の方向での歪は、a−格子定数以外の格子定数を用いて、又は2以上の格子定数を用いて測定され得る。複数の層は、ひとつの格子定数について一致するが他の格子定数については歪むことがあり得る。
Eg ABC=xEg AC+(1−x)Eg BC+x(1−x)B
ここでBはバンドギャップボウイングパラメータであり、バンドギャップ対組成直線の全ての非ゼロ曲線を説明する。ボウイングパラメータがゼロの場合、バンドギャップと組成との関係はヴェガード則(Vegard’s law)の関係として参照される。アルミニウム、インジウム、ガリウム及び窒素の3元系合金(即ち、ホウ素を含まない合金)で低インジウム組成(例えば30%未満のInN)合金は、通常ヴェガード則に従うバルク格子定数を持つ。
ウルツ鉱型III族窒化物層は大きな分極性を示し、温度及び組成の関数である自発的コンポーネント及び層の歪の関数である圧電性コンポーネントを含む。異なる層間の境界で分極性が不連続化することは、分極誘導シート荷電及び電場を与える結果となる。BNを添加することで、GaN/BInGaN境界での分極を不連続性とすることは、GaN/InGaN境界と比べて、例えば、前記境界での歪を低減する。いくつかの実施態様による、GaN/BInGaN発光層/p−GaN二重へテロ構造では、適切なBN組成を選択することで、歪、バンドギャップエネルギ及び分極が少なくとも部分的に解消され得る。例えば、ひとつを固定してあとの2つは任意に設定し得る。従来のGaN/InGaN/GaNへテロ構造においては、歪、バンドギャップエネルギ及び分極のひとつのみが独立して変更できる。BNを添加することで装置の歪を低減することは、より高いInN組成でより厚い活性領域の成長を可能とする。
