最近的PtSe2单层的Pt（111）衬底的直接硒化的合成，为了重现ARPES实验结果的动机，我们调查，如果PtSe2膜可以直接生长在Pt衬底的顶部，或者如果一些缓冲结构将它们分开。我们计算了不同的生长可能性的电子性质，并得出结论，实验结果是不兼容的PtSe2单层直接在Pt（1 1 1）衬底的顶部上的生长。
Motivated by the recent synthesis of a PtSe2 monolayer by direct selenization of a Pt(1 1 1) substrate and in order to reproduce ARPES experimental results, we investigate if the PtSe2 film could have grown directly on top of the Pt substrate or if some buffer structure separates both of them. We calculate the electronic properties for different growth possibilities and come to the conclusion that the experimental outcome is not compatible with the growth of a PtSe2 monolayer directly on top of the Pt(1 1 1) substrate.
