超越Fowler-Nordheim模型：金属纳米结构的谐波产生
Beyond Fowler-Nordheim model: Harmonic generation from metallic nano-structures
摘要：
已知与电磁场相互作用的金属结构表现出类似于原子和分子中发现的性质，例如多光子和隧道电离。开发这种相似性超出了电子发射电流，我们推广了著名的福勒-诺德海姆模型，并预测迄今未被识别的非线性光学响应源暴露于强光脉冲照射的纳米结构。
英文摘要：
Metallic structures interacting with electromagnetic fields are known to exhibit properties similar to those found in atoms and molecules, such as multi-photon and tunnel ionization. Developing this similarity beyond the electron emission current, we generalize the wellknown Fowler-Nordheim model, and predict heretofore unrecognized source of nonlinear optical response from nano-structures exposed to illumination with intense optical pulses.
