Description
Tm,f=T0(1-σSL/(L0<r>))であり、
式中、Tmは粒径(例えば、半径)rを有するフィルムの融点であり、T0は銀膜のバルク融解温度であり、σSLは固液界面エネルギーであり、L0は、融合のバルク潜熱である。しかしながら、薄膜積層体環境における真空圧力が考慮されても、この等式から予測されるものとTm、fの実験的に導かれた値との間に大きな差がある。これに対する1つの考えられる理由は、曲率効果又は非平衡効果による固液界面エネルギーの変化であるかもしれない。実際に、レーザー光は、表面プラズモン励起を介してAg/絶縁体フィルム界面に結合し、それによって集合的な電子振動が、レーザー光子の効率的な吸収を促進する。
・レーザーモード:ピコ秒以下、より好ましくは1、10、又は100フェムト秒単位(ただし、場合によっては更に短い)の幅のパルス。特定の例示的実施形態では、パルスモード持続時間は、10-12秒、より好ましくは1、10、又は100フェムト秒単位であってもよい。数ピコ秒未満(例えば、9ピコ秒未満、より好ましくは5ピコ秒未満、更により好ましくは1~3ピコ秒以下)が好ましい。1つの例示的な持続時間は、100~500フェムト秒(より好ましくは100~300フェムト秒、例えば、100又は200フェムト秒)である。1フェムト秒未満の持続時間において、例えば、約30kW/cm2の見かけの閾値が満たされないため、本明細書に記載される結果を達成するには、電力密度は、一般には低すぎることになる。
・レーザータイプ:エキシマレーザー(例えば、チャープモードで操作)。いくつかの例では、SHG(第二次高調波発生)レーザーに対するタンデムTi-サファイヤも使用することができる。
・電力密度:少なくとも約30kW/cm2、より好ましくは少なくとも約50kW/cm2。電力密度は、好ましくは、フィルムに対する損傷又は傷跡を回避するように選択される。50kW/cm2では、50%を超える結晶化が達成された。
・波長:一般に、355~500nmの波長を使用することができる。サンプルを、355nmの波長のエキシマレーザーを用いて作製した。また、サンプルを、400nmのSHGレーザーを用いて作製した。場合によっては、405nmのGaNレーザーを使用することができる。
・ビームプロファイル:均一フラットトップ(HFT)。HFTビームプロファイル(例えば、ガウシアンビームプロファイルと比較して)は、有利には表面に顕微鏡的傷跡を残さず、耐食性の改善が観察された。
・ビームサイズ:好ましくは<500マイクロメートルであり、特定の例示的実施形態では、鋭利なビームが可能である。
・促進される吸収機構:界面及びバルクAgプラズモン媒体(例えば、積層体内に別個の吸収層を有することによって支援される熱プロファイルを使用することと比較して)。この方法は、有利には、一重、二重、及び三重の銀積層体上で良好に機能する。特定の例示的実施形態は、有利には、別個の吸収層を欠いており、その代わりに、上記のようにアサーマルである。
・ビーム光学:非常に高い走査速度の移動ターゲットを伴う、ガルバノレーザーの可能性がある。いくつかの実装では、Shafter-Kirchoofのライン発生器を使用することができる。
・フルエンス範囲:0.5~5J/cm2、より好ましくは0.5~3J/cm2、及び場合によっては最小0.1~0.6J/cm2
・繰り返し率:1~100KHz
・ショット間安定性:0.5~1%rms
・長期駆動:0.1-0.5%rms
・レーザー処理環境:レーザー処理は、周囲空気、窒素環境、完全又は部分的真空下などで行われてもよい。
