Description
実施例1
Commun.)2003年、p.734参照)。式中、ωはcm-1を単位とするRBM周波数であり、dはnmを単位とする単層カーボンナノチューブの直径であり、また、凝集作用の影響も考慮された式である。130〜350cm-1のRBC周波数は0.6〜1.8nmの直径に相当する。しかしながら、1586cm-1の主ピーク(Gバンド)の左に出現する1552cm-1のショルダーピークは、グラファイトのE2gモードのスリットによるものである。さらに、このショルダーピークは単層カーボンナノチューブの特性散乱モードの1つでもある(例えば、A.カスヤ(Kasuya)、Y.ササキ(Sasaki)、Y.サイトー(Saito)、K.トージ(Tohji)、Y.ニシナ、フィジカル・レビュー・レターズ(Phys. Rev. Lett.)1997年、78:p.4433参照)。これらの特性ピークの他に、1320cm-1に出現するピークは欠陥によって誘発されるモード、即ち、Dバンドに相当し、これはサンプルに含まれる無定形炭素などの欠陥に相当する。さらに、このG/D比はSWNTの純度を評価するための指標であり、この比はSWNTの純度が増加するにつれて大きくなる(例えば、H.カタウラ(Kataura)、Y.クマザワ(Kumazawa)、Y.マニワ(Maniwa)、Y.オオツカ(Ohtsuka)、R.セン(Sen)、S.スズキ(Suzuki)、A.アチバ(Achiba)、カーボン(Carbon)2000年、38:p.1691参照)。
