…(1) Photon (quantum) effect type This type utilizes the interaction between incident photons and bound or free electrons in a material. The phenomenon in which an incident photon is absorbed by the surface of a material and an electron is released to the outside as a result is called the external photon effect (external photoelectric effect), and the released electron is called a photoelectron. The energy of one photon is expressed as h ν ( h is Planck's constant, ν is the frequency of light), but photoelectrons are not released unless this value is equal to or exceeds the "threshold potential" E t determined by the surface of the material that detects the light. … *Some of the terminology that refers to the "external photon effect" is listed below.

…(1)光子(量子)効果型 入射光子と物質内の束縛電子,あるいは自由電子との相互作用を利用したものである。入射光子が物質表面に吸収され,その結果,外部に電子を放出する現象を外部光子効果(外部光電効果),また放出される電子のことを光電子と呼ぶ。光子1個のもつエネルギーはhν(hはプランク定数,νは光の振動数)で表されるが,この値が光を検出する物質表面で決まる“しきいポテンシャル”Et以上でないと光電子は放出されない。… ※「外部光子効果」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 |
