光电效应 Photoelectric effect

(重定向自Photoelectric)
光电效应示意图:来自左上方的光子冲击到金属板,将电子逐出金属板,并且向右上方移去。
海因里希·赫兹
汤姆森量度粒子电荷质量比的光电效应实验设备。[注 2]
匈牙利物理学家菲利普·莱纳德

光电效应Photoelectric Effect)是指光束照射在金属表面会使其发射出电子的物理效应。发射出来的电子称为「光电子」。要发生光电效应,光的频率必须超过金属的特征频率。

1887年,德国物理学者海因里希·赫兹发现,紫外线照射到金属电极上,可以帮助产生电火花。1905年,阿尔伯特·爱因斯坦发表论文《关于光产生和转变的一个启发性观点》,给出了光电效应实验数据的理论解释。爱因斯坦主张,光的能量并非均匀分布,而是负载于离散的光量子(光子),而这光子的能量和其所组成的光的频率有关。这个突破性的理论不但能够解释光电效应,也推动了量子力学的诞生。由于「他对理论物理学的成就,特别是光电效应定律的发现」,爱因斯坦获颁1921年诺贝尔物理学奖。

Photoelectric effect 光电效应

(重定向自Photoelectric)
Diagram of the maximum kinetic energy as a function of the frequency of light on zinc
Work function and cut off frequency
Heinrich Rudolf Hertz

The photoelectric effect or photoemission is the production of electrons or other free carriers when light shines upon a material. Electrons emitted in this manner can be called photoelectrons. The phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry.
