2DCC User Research Highlight

With the emergence of the internet of things, the risk of information loss or security threat heightens. Conventional software crypto modules are powerful, but consume an enormous amount of energy, necessitating innovation in materials, devices, and architectures to produce next-generation secure low-energy electronics. Deriving inspiration from nature, we have demonstrated a low-power bioinspired crypto engine based on atomically thin multifunctional MoS2 memtransistors.

Project Summary:  Materials composed of nitrogen-doped carbon are useful as catalyst supports due to their low cost, low density, and enhanced metal−support interaction. One way to synthesize catalytic single atoms and nuclei on these supports is via vapor phase deposition processes. Here, density functional theory (DFT) was used to evaluate the effects of N doping and oxidation of graphene on the adsorption and dissociation of trimethyl- (methylcyclopentadienyl) platinum (MeCpPtMe3), which is a commonly used precursor in vapor deposition of platinum.

Project summary: The electronic and optical properties of 2D materials can be strongly influenced by defects, some of which can find significant implementations, such as controllable doping, prolonged valley lifetime, and single-photon emissions.

Project summary: Transition metal dichalcogenides (TMDs) are seen as potential candidates for complementary metal oxide semiconductor (CMOS) technology in future nodes.

Project Summary: Magnetism in quantum materials creates a fertile ground for the exploration of fundamental spin-based phenomena, with applications in spintronics, magnetic memory, and quantum information technology. This is exemplified by the recent development of magnetic topological materials.

Project Summary: Common metals bounce incident light in the infrared range. In our recent experiments, we discovered that a special class of metals, so called nodal metals hosting the two-dimensional electronic structure with van Hove singularities, support waveguiding of infrared energy in their bulk. This novel plasmonic effects is observed over an extended frequency range in near infrared.

Project Summary: The ability to engineer potential profiles of multilayered materials is critical for designing high-performance tunneling devices such as ferroelectric tunnel junctions (FTJs). FTJs promise electrically switchable memories, sensors, and logic devices. However, traditional FTJs comprising metal/oxide heterostructures only exhibit modest tunneling electroresistance (TER; usually <106), which is limited by defect states and interface trap states. In this work, the group led by Prof.

Project Summary: The emergence of magnetism via a magnetic proximity effect (MPE) allows the realization of magnetic properties in non-magnetic materials, leading to properties not observed in the bulk nor achievable via magnetic doping. MPEs are of particularly significant interest in heterostructures that interface a topological insulator with a ferromagnet.

Project Summary: In-situ spectroscopic ellipsometry (SE) presents a powerful tool to access precise measurements of film thickness, stoichiometry, and growth temperature at once in-operando in a non-destructive way.

Project Summary: The van der Waals (vdW) layered chalcogenides have attracted significant interest for photonic and optoelectronic applications due to their strongly anisotropic properties.
