Magnetic two-dimensional (2D) materials are promising building blocks for realizing ultra-compact spintronic devices with enhanced performance. Their study is also expected to open new perspectives on a more versatile modulation of magnetic properties, beyond what can be achieved in traditional...

The stacking of different two-dimensional (2D) materials such as graphene and hexagonal boron nitride (h-BN) allows to realize novel 2D heterostructures with tailored properties for application in atomically thin optoelectronic, electronic, and sensing devices. To achieve a high-density, bottom-up...

Phase change materials (PCM) are compounds employed in non-volatile random-access memory and rewriteable optical storage media thanks to the rapid and reversible transformation between the amorphous and crystalline states. GeSbTe alloys are the most studied PCMs and consist of lamellae separated by...

Oxide electronics is a rapidly developing field of research, yielding opportunities for transparent devices, solar-blind UV sensors, or energy-efficient power electronics. Currently, Ga₂O₃ is considered a champion semiconducting material for high-voltage power electronics that is predicted to...

Hexagonal boron nitride (h-BN), an insulating two-dimensional material, is a promising building block as a dielectric layer in novel, atomically thin and flexible two-dimensional (2D) electronic devices such as graphene-based capacitors or field-effect transistors. Furthermore, it is preferentially...

Graphene offers new opportunities to improve the performance and functionalities of optoelectronic devices based on III−V compound semiconductors. The transparency and high in-plane electrical conductivity of graphene and few-layer graphene films is of interest for the fabrication of contact layers...

Turning chalcogenide compounds, such as germanium telluride (GeTe), into thermoelectric materials that convert waste heat into electricity requires careful balancing of conflicting material properties. Epitaxial growth of GeTe has revealed some interesting challenges, especially if it comes to...

Graphene nanoribbons (GNRs) are promising for applications in nanoelectronics due to their unique properties including an electronic band gap which is inversely proportional to their width. Therefore, achieving a controlled and high-quality synthesis of GNRs is anticipated to be of great importance....

Over the last century, society has benefited greatly from technological advances. However, this progress has come with many unintended consequences such as pollution of air and water. Hence the need to monitor air pollution, e.g., by nitrogen dioxide (NO₂) from Diesel cars or ozone (O₃) produced in...

Phase change materials (PCMs) are employed in non-volatile random access memory for the rapid and reversible transformation between the amorphous and crystalline state that display large differences in electrical properties. The most interesting compounds exhibiting PCM properties are Te-based...
