Andrivo RUSYDI

Assistant Professor

• Study of interplay of spin, charge, orbital and lattice degrees of freedom at interface and surface of novel complex systems and nanostructured strongly correlated electron systems, such magnetic materials, high temperature superconductors, organic semiconductors, and molecular electronics materials.

• Develop in-situ synchrotron-based characterizations including resonant soft X-ray magnetic scattering, spectral generalized magneto-optical spectrocopic ellipsometry (from mid-infrared to vaccum-ultraviolet) and angular resolved photoemission spectroscopy, and in-situ (ultra) film growth (atomically layer-by-layer molecular beam epitaxy) at Singapore Synchrotron Light Source.
