Description
一例では、略44μmの石炭粒子を有するスラリーを、略0.04g/mlの濃度で懸濁させた。スラリーは、略40mMの鉄濃度を有していた。石炭スラリーを、104℃の温度及び100mA/cm2の電流で電気分解した。
他の例では、シリコンウェーハを前処理して、電気分解した石炭ではなくて、IPAをウェーハ上に堆積させた。ウェーハを炉内において、1slpmの流量のアルゴンで20分間にわたってパージした。そして、アルゴンを流して、炉を30分間で800℃に昇温させた。0.8slpmの水素・窒素の流れで、800℃の温度を30分間にわたって維持した。そして、1slpmのアルゴン流で、系を室温に冷却した。
更に他の例では、略0.04g/mlの濃度で懸濁させた略210〜249μmの石炭粒子を有するスラリーを作製した。スラリーは略40mMの鉄濃度を有していた。石炭スラリーを104℃の温度、100mA/cm2の電流で電気分解した。結果物の電気分解石炭をグラフェン合成に用いた。
更に他の例では、異なる条件で電気分解した石炭のサンプル、また未加工の石炭を用いて合成を行った。これらの条件を表1にまとめる。
更に他の例では、5.8mgの電気分解石炭、6mlのイソプロパノールでスラリーを作製した。スラリーを5分間超音波処理して、20倍に希釈した。シリコンウェーハをアセトン及び蒸留水で洗浄して、100μlのスラリーをウェーハ上に堆積させた。同じ前処理プロセスを用いて、未加工の石炭粒子を堆積させた第二のシリコンウェーハも作製した。
