元素周期表中元素的热laser蒸发
Thermal laser evaporation of elements from across the periodic table
摘要：
我们提出并证明，热激光蒸发可以应用于周期表中的所有固体，非放射性元素。通过沉积薄膜，我们实现了超过1埃/秒的生长速率与输出激光功率小于500 W，使用相同的光束参数为许多不同的元素。在所考察的功率范围内，光源温度与激光功率呈线性关系。对于大多数测试的元素，使用独立源可以实现高生长速率，无需坩埚。
英文摘要：
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.
