Scientific focus
We investigate surfaces of complex and ternary materials, including cleaved single crystals and perovskite oxides such as titanates, tantalates and niobates. Polar surfaces, ionic crystals and organohalide perovskites offer access to reconstruction, segregation, self-trapped charges and other electronic phenomena that are absent in simpler materials. We also explore scintillating and layered materials when their surface properties pose interesting fundamental questions.
