…Electrons fill these k states in order from lowest energy to highest energy, and when all the electrons have been filled, they will be exactly at the Fermi surface. This surface is also an isoenergy surface, and the corresponding energy is called the Fermi energy. The Fermi energy of a metal is much larger than thermal energy, so even if the temperature rises slightly, there is not much change other than the way the electrons near the Fermi surface are filled up a little. … *Some of the terminology that mentions "Fermi energy" is listed below.

…電子はこれらのkの状態をエネルギーの低いところから順に詰めていくが,全電子を詰め終えたとき,ちょうどフェルミ面まで詰まることになる。この面は等エネルギー面でもあり,対応するエネルギーをフェルミエネルギーFermi energyと呼ぶ。金属のフェルミエネルギーは熱エネルギーに比べてはるかに大きいので,多少温度が上がっても,フェルミ面近くの電子の詰まり方が少しぼやける程度であまり変化はない。… ※「Fermi energy」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
