Description
本願は、2016年5月13日に出願された米国仮出願第62/336,228号の利益を主張するものであって、その内容は、参照によって全体として本明細書に組み込まれる。
図2に反応機構の構成を示す。MoO3粉末(10mg)をアルミナボートに入れた。予め洗浄したSiO2/Si基板を、ボート上に下向きにして置いた。ボートを石英反応管の中心に装填した。組み立てられた反応管を管状炉内に配置し、N2及びH2Se反応ガスラインに接続した。それら反応ガスラインは、マスフローコントローラ及び排気ラインによって制御された。反応の前に、真空/N2サイクルで管をパージし、その後、チャンバをN2ガスで再充填し、キャリアガス流を90sccmに維持した。管炉を作動させ、図3に示す予めプログラムされた温度プロファイルが続いた。炉が730℃に達すると、H2Seを10sccmの流量で導入した。
