5. Conclusions

The aim of the two articles [AF 3 716] [AF 3 717] is to introduce the reader to the essential concepts involved in describing, calculating and measuring the electronic properties of solid surfaces. Over the past half-century, surface science has made remarkable progress in characterizing these surfaces, thanks in particular to developments in ultra-high vacuum production technologies. Driven by the need for new applications, it has generated considerable industrial spin-offs, particularly in the field of microelectronics. For many systems, the state-of-the-art involving experiments...
