Description
当該膜が、少なくとも1つのIII−V族化合物または少なくとも1つのII−VI族化合物または1つのIV族化合物、好ましくは、少なくとも1つのIII−V族化合物または少なくとも1つのII−VI族化合物を含む、組成物を提供する。
(I)II−VI族元素もしくはIII−V族元素もしくはIV族元素またはIV族元素を、前記グラファイト基板の表面に、好ましくは、分子線により、供給する工程と、
(II)グラファイト基板の表面上にIII−V族もしくはII−VI族膜またはIV族化合物をエピタキシャル成長させる工程と
を含む、製造方法を提供する。
(I)前記基板上に基層膜を供給する工程であって、前記基層膜が、グラフェンの格子不整合に対し、2.5%以下、好ましくは1%以下の格子不整合を有する元素または化合物を含む工程と、
(II)前記基層膜をII−VI族元素またはIII−V族元素と、好ましくは、分子線を介して接触させ、III−V族またはII−VI族膜を成長させる工程と
を含む、方法を提供する。
(a)グラファイト基板、
(b)グラフェンの格子不整合に対し、2.5%以下、1%以下の格子不整合を有する元素または化合物を含む基層膜、および
(c)III−V族化合物またはII−VI族化合物またはIV族化合物、好ましくは、III−V族化合物またはII−VI族化合物を含む膜
を含む、組成物を提供する。
(a)グラファイト基板、
(b)GaSb、InAs、AsSb、GaN、SbBi、AlAs、AlSb、CdSeまたはSb、好ましくは、GaSb、InAs、AsSb、GaN、SbBiまたはSbを含む基層膜、および
(c)III−V族化合物またはII−VI族化合物またはIV族化合物、好ましくは、III−V族化合物またはII−VI族化合物を含む膜
を含む、組成物を提供する。
III−V族化合物とは、III族から少なくとも1つのイオンと、V族から少なくとも1つのイオンとを含むものを意味する。同様に、II−VI族化合物とは、少なくとも1つのII族イオンと、少なくとも1つのVI族イオンとを含むものである。本願において、用語「II族」は、典型的なIIa族およびIIb族周期(すなわち、アルカリ土類系およびZn系元素)の両方を包含する。例えば、InGaAs(すなわち、三元化合物)など、各族から2つ以上のイオンが存在していてもよい。四元以上の化合物も存在していてもよい。
商業的に重要な薄膜を製造するためには、薄膜は基板上でエピタキシャル成長させることが重要である。本明細書において、これは、グラフェン基板と薄膜との良好な格子整合を確保にすることにより、または、任意に、下記に詳述するような基層膜の格子整合を介して実現される。
他の半導体膜が存在できるようにし、且つ、本明細書における可能性を最大限にするため、本発明者らは、半導体薄膜と基板との間に中間層または基層の使用を提案する。この方法が好ましく使用されるのは、半導体がグラファイト基板と格子整合できない場合、または特定の半導体が何らかの理由により、例えば、その成分のいずれも、グラファイト表面をカバーするのに十分な界面活性剤作用を持たないなど、グラファイト表面上に直接薄膜が形成されない場合である。
本発明の半導体膜は、少なくとも1つのIII−V化合物または少なくとも1つのII−VI化合物またはSiCなどのIV族化合物から形成される。
本発明において成長させる膜は、厚さ250nm〜数ミクロン、例えば、0.5〜10ミクロン、より好ましくは、1〜5ミクロンであってもよい。膜の表面積は、成膜に使用する装置と基板のサイズによってのみ制限される。表面積はまた、更に後述するように、膜を成長させる孔のサイズによって決定される場合もある。
まず初めに、グラファイト基板上に本発明の膜を直接成膜することを検討する。本発明の膜は、基板または基層上にエピタキシャル成長する。膜は、共有結合、イオン結合または準ファンデルワールス結合により、土台となるグラファイト基板に付着する。従って、基板と膜の接合部で、結晶面がエピタキシャルに形成される。これらが互いに同一の結晶方位に積み重なることにより、膜をエピタキシャル成長させる。
本発明の膜は、幅広い実用性を有する。本発明の膜は半導体であるため、半導体技術が有用であるあらゆる分野において用途提供が期待できる。それらは、主として、エレクトロニクスおよびオプトエレクトロニクス用途(例えば、太陽電池、光検出器、発行ダイオード(LEDs)、導波管およびレーザー)において有用である。
図1A〜1Dは、半導体原子が、グラフェン上の1)H−およびB−サイト(図1A、1Bおよび1D)、並びに2)H−またはB−サイト(図1C)上方に配置されている場合の原子配列を示す。図1Eでは、III−V族半導体(並びにSiおよびZnO)のバンドギャップエネルギーを、それらの格子定数に対しプロットしている。有色の垂直実線(破線)は、グラフェンに対し4つの異なる原子配列(図1A〜1D)を有する立方晶(六方晶)に関するグラフェンとの完全な格子整合を実現するであろう理想結晶の格子定数を表している。いくつかの二元半導体の場合、一つの示されている原子配位では、グラフェンとの格子不整合が非常に小さい(例えば、InAs、GaSbおよびZnO)。GaAsなどの他の二元半導体に関しては、格子不整合がかなり大きく、(図1bまたは図1cのように)2つの異なる原子配位の中間となる。多くの三元、四元および五元半導体が、グラフェンに対し完全に格子整合できることが図から理解できる。
薄膜は、通常のAlフィラメントセル、Ga二重フィラメントセル、In二重フィラメントセル(SUMO)、Asバルブ付きクラッカーセルおよびSbバルブ付きクラッカーセル(二量体および四量体の割合を固定させる)を備えたバリアンゲンIIモジュラー(Varian Gen II Modular)分子線エピタキシー(MBE)システムにおいて成長させる。本研究では、ヒ素の主要種はAs2であり、アンチモンはSb2である。
p型ドーピングには、Beを使用する。GaInAsSbエピ層用のn−ドーパントとしてはTeを使用する。Beセル温度は、公称p+型ドーピング濃度が1×1018cm-3となる990℃に設定し、また、Beセル温度は、公称p型ドーピング濃度が9×1016cm-3となる940℃に設定する Teセル温度は、公称n型ドーピング濃度が1×1018cm-3となる440℃に設定する。
