Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, promise new physical properties such as quantum spin Hall effect. While there have been many claims of growth of germanene, the lack of precise structural characterization of

Au-Cu bimetallic nanoparticles (NPs) grown on TiO 2 (110) have been followed in-situ using grazing incidence x-ray diffraction and x-ray photoemission spectroscopy from their synthesis to their exposure to a CO/O 2 mixture at low pressure (P < 10-5 m

Report

Growth of germanium-silver surface alloys followed by in situ scanning tunneling microscopy: Absence of germanene formation

Autor: Zhang, Kai, Bernard, Romain, Borensztein, Yves, Cruguel, Hervé, Prévot, Geoffroy

Publikováno v: Physical Review B: Condensed Matter (1978-1997), American Physical Society, 2020, 102, pp.125418

Theoretical studies have shown that new physical properties such as tunable gap openings or quantum spinHall effects could be expected from group-IV graphene analogs (silicene, germanene, stanene). While therehave been numerous studies of growth of s
