摘要

我们提出并证明热激光蒸发可以应用于元素周期表中所有固体,非放射性元素。通过沉积薄膜,我们实现了超过1埃/秒的生长速度,输出激光功率小于500瓦,使用相同的光束参数对许多不同的元素。在检测的功率范围内,光源温度随激光功率呈线性变化。对于大多数测试元素,使用独立的来源可以实现高增长率,从而消除了对坩埚的需要。

Thermal laser evaporation of elements from across the periodic table
We propose and demonstrate that thermal laser evaporation can be applied to all solid, non-radioactive elements in the periodic table. By depositing thin films, we achieve growth rates exceeding 1 angstrom/s with output laser powers less than 500 W, using identical beam parameters for many different elements. The source temperature is found to vary linearly with laser power within the examined power range. High growth rates are possible using free-standing sources for most of the elements tested, eliminating the need for crucibles.
