回顾了短暂时间间隔测量的历史。条纹概念的引入、电光源和电子仪器的使用、激光的出现使能测量到的短暂时间间隔大大缩短。由于对撞脉冲锁模和啁啾脉冲压缩新概念的提出,人们将脉冲宽度压缩到了几个飞秒。介绍了自锁模钛宝石激光器的锁模、放大和调谐的工作原理以及飞秒技术在物理学、生物学、化学控制反应、光通讯等领域中的应用。 相似文献

The heteroepitaxial growth of multilayer Cu/Pd(100) thin film via
pulse laser deposition (PLD) at room temperature is simulated by
using kinetic Monte Carlo (KMC) method with realistic physical
parameters. The effects of mass transport between interlayers, edge
diffusion of adatoms along the islands and instantaneous deposition
are considered in the simulation model. Emphasis is placed on
revealing the details of multilayer Cu/Pd(100) thin film growth and
estimating the Ehrlich--Schwoebel (ES) barrier. It is shown that the
instantaneous deposition in the PLD growth gives rise to the
layer-by-layer growth mode, persisting up to about 9 monolayers (ML)
of Cu/Pd(100).

一、前言众所周知,在金属电对M-M~(m+)体系中加入沉淀剂S~(2-)或X~-离子,难溶硫化物M_aS_b(s)或卤化物MX_b(s)的生成,降低了金属的电极电位。对于这类电对的标准电极电位数据在电极电位顺序表中有较详细的介绍,且在该表的内容构成方面占有一定的比重(约占10%)。另一方面,在非金属电对S-S~(2-)或X_2-X~-体系中 相似文献
