Ferromagnetic FexGe1−x with x = 2%–9% are obtained by Fe deposition onto Ge(001) at high temperatures (500 °C). Low energy electron diffraction (LEED) investigation evidenced the preservation of the (1 × 1) surface structure of Ge(001) with Fe

Catalysts are frequently used as pelletized powdered materials, but rarely as thin films. The present work reports the use of 2D h-boron nitride on few layers defective graphene (h-BN/fl-G) films of about 10 nm thickness as base catalyst for the synt

The emerging field of electronics based on ferro-functional materials relies on driving effectively and predictably a ferroelectric system between different polarization states through bias applied to metallic contacts. This requires detailed underst

The orientation of polarization in ferroelectric thin films is important for applications of these materials in nonvolatile memory and field-effect transistors with ferroelectric gates, and in catalysis and photocatalysis. One means of control is to

A single atomic Au layer is grown epitaxially on a Ge(001) surface featured by (2 × 1) reconstruction. The low energy electron diffraction pattern of the Au/Ge(001) surface indicates the formation of a square structure with the length of crystalline
