Abstract: ３ミクロンを超える赤外線スペクトルの領域で特に有用なエレクトロクロミック装置は、順に、後方ガラス基板（１）、少なくとも５０％の赤外線反射率を有するフィルム電極（２）、イオン貯蔵層（３）、及び、イオン透過層（４）を含む。エレクトロクロミック酸化タングステン層（５）は、少なくともある程度の結晶度、シリコン前方電極（６）、及び、反射防止コーティング（７）を有する。層（５）が非荷電状態においては、全ての層（３〜７）は透明であり、大部分の入射光は（２）で反射される。荷電状態に入ると、層（５）は、吸光率及び屈折率に顕著な増加を示す。裸の層（５）を組み込んだ装置においては、この裸の層が前面において反射率を非常に大きく増加させるので、光吸収の増加は覆い隠されがちであり、結果的に装置の反射率の増加をもたらす。層（６）は、屈折率整合層（６）として作用し、それによって層（５）の前面で反射する光が少なくなり、荷電された層（５）に吸収される光が両方の透過方向により多く透過されるので反射率を減少させる。

Abstract: <P>PROBLEM TO BE SOLVED: To provide a p-type nitride compound semiconductor whose contact resistance against an electrode metal is low and which has a high carrier concentration.  <P>SOLUTION: A 3-5 compound semiconductor in which a p-type dopant is doped and which is represented by a general formula In<SB>x</SB>Ga<SB>y</SB>Al<SB>z</SB>N (0≤x≤1, 0≤y≤1, 0≤z≤1 and x+y+z=1) is heat-treated in a mixed gas atmosphere comprising gas comprising oxygen and gas comprising hydrogen. Thus, the p-type nitride 3-5 compound semiconductor whose contact resistance against the electrode metal is low, which is superior in electric properties such an ohmic properties and which has a high carrier concentration can be manufactured.  <P>COPYRIGHT: (C)2004,JPO
