| Abstract Scope |
The synthesis of high-quality NbSe2 thin films is of interest for applications in thermomagnetic energy conversion. Molecular beam epitaxy (MBE) is a promising route towards this aim as it provides fine control over growth conditions. For thermomagnetic energy conversion, the 2H phase of NbSe2 is desired. However, a number of competing phases, such as metastable 1T-NbSe2, are found to form during synthesis by MBE. We will report on the effect of processing parameters on the chemical makeup of synthesized thin films, with a goal of optimizing growth conditions for thermomagnetic energy conversion. In-situ X-ray photoelectron spectroscopy and reflection high energy electron diffraction will be performed to analyze the intrinsic chemical composition and growth mode of the synthesized material. To characterize the Nernst coefficient, which quantifies the material’s ability to generate thermomagnetic power, ex-situ measurements will be carried out on NbSe2 films grown on insulating muscovite. |
