…One energy band can accommodate twice the number of electrons N , the number of unit cells in the crystal, but a completely filled energy band (also called a filled band or valence band) cannot carry electric current. Therefore, the Fermi level is in the forbidden band, and there is a completely empty energy band (conduction band).… *Some of the terminology that mentions "valence band" is listed below.

…一つのエネルギー帯には結晶の単位胞の数Nの2倍の電子が収容されるが,完全に満たされたエネルギー帯(充満帯filled band。価電子帯valence bandともいう)は電流を流すことはできない。したがって,フェルミ準位が禁止帯にあって,充満帯と完全に空のエネルギー帯(伝導帯conduction band。… ※「valence band」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 |
