Magnetic anisotropy and magnetic exchange interactions are crucial parameters that characterize the hybrid metal–organic interface, a key component of an organic spintronic device. It is shown that the incorporation of 4f RE atoms to hybrid metal–organic interfaces of CuPc/REAu2 type (RE = Gd, Ho) constitutes a feasible approach toward on‐demand ma...

In the realm of materials science and nano-technology, the pursuit of the scalable preparation of high-quality monolayers of two-dimensional (2D) materials is a significant challenge. Despite the widespread interest sparked by the unique quantum mechanical effects in these materials, achieving scalable and controlled syntheses remains hindered by a...

Two-dimensional (2D) materials represent the ultimate limit of miniaturization along the vertical direction, where several fascinating quantum mechanical effects—that are otherwise inaccessible—appear, generating widespread interest in fundamental and applied research. However, the preparation of scalable monolayers is a requirement that is hindere...

Nanobubbles naturally formed at the interface between 2D materials and their substrate are known to act as exciton recombination centers because of the reduced bandgap due to local strain, which in turn scales with the aspect ratio of the bubbles. The common understanding suggests that the aspect ratio is a universal constant independent of the bub...

Unprecedented nationwide lockdowns were adopted because of the COVID-19 pandemic. Understanding the socioeconomic impact of the past and future restrictions while assessing the resilience of a local economy emerged as a worldwide necessity. To predict the economic and environmental effects of the lockdowns, we propose a methodology based on the wel...

We have investigated the electronic structures of axially oxo functionalized titanylphthalocyanine (TiOPc) on Ag(111) by X-ray and ultraviolet photoelectron spectroscopy, two-photon photoemission, X-ray absorption spectroscopy, and X-ray magnetic circular dichroism. Furthermore we use complementary data of TiOPc on graphite and planar copper phthal...

The synthesis of graphene nanoislands with tailored quantum properties requires an atomic control of the morphology and crystal structure. As one reduces their size down to the nanometer scale, domain boundary and edge energetics, as well as nucleation and growth mechanisms impose different stability and kinetic landscape from that at the microscal...

Materials that exhibit ferromagnetism, interfacial stability, and tunability are highly desired for the realization of emerging magnetoelectronic phenomena in heterostructures. Here we present the GdAg2 monolayer alloy, which possesses all such qualities. By combining X-ray absorption, Kerr-effect and angle-resolved photoemission with ab-initio cal...
