Abstract
【解決手段】基板(12)と円柱構造とを含み、円柱構造が、半導体を含み、かつ円柱構造の縦軸が、基板(12)にほぼ垂直となるように基板(12)上に配設される物品を開示する。電子輸送皮膜(14)がその上に配設された基板(12)を含み、電子輸送皮膜(14)が円柱構造を含む電極(10)を開示する。
【選択図】図1
Description
以下の実施例1〜3は、膨張熱プラズマの反応チャンバ内の圧力を約45〜約100ミリトル(mT)に変化させた場合の、ガラス基板上での二酸化チタンの円柱構造形成を例証するために行われた。使用されたに酸化チタンの前駆体は、塩化チタンまたはチタンイソプロポキシドであった。膨張熱プラズマ発生器内にアルゴンを供給した。アノードから約3cmの反応チャンバ内に前駆体と共に酸素を供給した。堆積中の基板温度は、約100〜約150℃に変化させることができる。これらの例では、基板を約150℃の温度に維持した。反応チャンバ内の圧力は、45mTまたは100mTに維持した。堆積済み材料は性質が非晶質なため、450℃でさらに焼結後、必要な化学量論的組成を有する所望の材料に変換し、それによってアナターゼを含む結晶円柱構造を形成した。焼結時間は30分であった。このようなアニーリング後に得られた円柱構造は、一般に完全な結晶である。場合によっては、円柱構造は非晶質相の小部分を有する。
