Atomistic mechanism and interface-structure-energetics of van der Waals epitaxy demonstrated by layered alpha-MoO3 growth on mica
Faezeh A. F. Lahiji, Davide G. Sangiovanni, Biplab Paul +5
Unlike conventional epitaxy, van der Waals epitaxy (vdWE) allows nearly stress-free growth of thick films with highly oriented crystals without dislocations even for large film-sub…
Questioning van der Waals Epitaxy of Non-Layered Materials on Mica: The Case of ScN
Susmita Chowdhury, Faezeh Alijan Farzad Lahiji, Mikael Ottoson +6
Growing stress-free epitaxial films by van der Waals epitaxy (vdWE) is of interest for realizing flexible optoelectronics and energy devices from freestanding epilayers. However, v…
Damage accumulation induced metal-insulator transition through ion implantation of ScN thin films
Charlotte Poterie, Marc Marteau, Per Eklund +3
Ion implantation is a powerful approach for tuning the electrical properties of materials through controlled doping and defect engineering, with applications in thermoelectrics and…
Morphology-engineered nanostructured silver- and antimony-telluride films for flexible thermoelectric generators
Ankit Kashyap, Conner Wallace, Geetu Sharma +7
Harvesting low-grade heat to electricity is attractive for powering wearable electronic devices. Here, we demonstrate nW-scale thermoelectric power generation in devices from thin…
Phase selection and texturing in molybdenum oxide films grown by reactive magnetron sputtering
Faezeh A. F. Lahiji, Biplab Paul, Grzegorz Greczynski +3
Molybdenum oxide films offer a rich variety of properties for diverse applications, but exclusive synthesis of desired phases is a major challenge. Here, we demonstrate that oxygen…
Fermiology and Band Structure of Oxygen-Terminated Ti3C2Tx MXene
Martin Magnuson, Per Eklund, Craig Polley
The class of two-dimensional carbides and nitrides known as MXenes exhibit remarkable electronic properties. Tailoring these properties, however, requires an in-depth understanding…
