论文摘要
原子加热是在能量沉积过程中受热尖峰效应控制的基本现象。这项工作通过使用耦合的经典振荡器模型而不是典型的热扩散模型，对热尖峰进行了另一种洞察力。沉积原子的温度曲线被振荡器振幅代替为能量描述。解决相关的部分微分方程（PDE）表明，从耦合的热振荡器到冷振荡器的能量转移效率基本上依赖于原子距离R和弹簧常数k。对阻尼波方程的解决方案进一步强调了能量传播过程中的局部热波动。
Atomic heating is a fundamental phenomenon governed by the thermal spike effect during energetic deposition. This work presented another insight into thermal spike using a coupled classical oscillator model instead of a typical heat diffusion model. The temperature profile of deposited atoms was replaced by oscillator amplitude as an energy descriptor. Solving associated partial differential equations (PDEs)suggests the efficiency of energy transfer from the coupled hot to cold oscillators essentially relies on the atomic distance r and the spring constant k. The solution towards the damped wave equation further emphasize that a localized thermal fluctuation during energy propagation.
