Colossal positive magnetoresistance in surface-passivated oxygen-deficient strontium titanite
Published 2015“…Here we report colossal positive magnetoresistance (CPMR) (>30,000% at a temperature of 2 K and a magnetic field of 9 T) discovered in degenerate semiconducting strontium titanite (SrTiO3) single crystals capped with ultrathin SrTiO3/LaAlO3 bilayers. The low-pressure high-temperature homoepitaxial growth of several unit cells of SrTiO3 introduces oxygen vacancies and high-mobility carriers in the bulk SrTiO3, and the three-unit-cell LaAlO3 capping layer passivates the surface and improves carrier mobility by suppressing surface-defect-related scattering. …”

Mitigating initial capacity loss for practical lithium-ion battery
Published 2021“…While numerous promising anode materials with optimized electrochemical performance, such as fast-charging capability and long-term stability have been developed, they still suffer from low initial Coulombic efficiency (ICE) due to solid electrolyte interphase (SEI) formation and lithium trapping, which impede their commercialization. In this thesis, new insights and strategies for the two mechanisms leading to initial capacity loss (ICL) based on different type of anode materials were investigated.…”
