- Abstract: A new two‐dimensional (2D) germanium dioxide film has been prepared. The film consists of interconnected germania tetrahedral units forming a bilayer structure, weakly coupled to the supporting Pt(111) metal‐substrate. Density functional theory calculations predict a stable structure of 558‐membered rings for germania films, while for silica films 6‐membered rings are preferred. By varying the preparation conditions the degree of order in the germania films is tuned. Crystalline, intermediate ordered and purely amorphous film structures are resolved by analysing scanning tunnelling microscopy images. Abstract : Ein 2D‐Germaniumdioxid‐Film aus miteinander verbundenen Germaniumdioxid‐Tetraedereinheiten, die eine zweischichtige Struktur bilden, die schwach mit dem tragenden Pt(111)‐Metallsubstrat gekoppelt ist, wurde hergestellt. Durch Variation der Präparationsbedingungen wird der Ordnungsgrad in den Germaniumdioxidfilmen eingestellt. Kristalline, zwischengeordnete und rein amorphe Filmstrukturen werden durch die Analyse von rastertunnelmikroskopischen Bildern aufgelöst.
