Research Interests

q-Plus sensor

noncontact Atomic force microscopy (nc-AFM): Recent developments in this experimental technique offer intriguing opportunities in materials research. nc-AFM offers for example molecular and submolecular resolution, enhanced capabilities of chemical identification, or measurement and control of the charge state of species adsorbed at surfaces. These capabilities offer a new angle of view on complex materials, which were often difficult to study by other experimental methods. My main aim is developing methodology for understanding the surfaces of binary and ternary oxides, and pointing out the opportunities offered by the nc-AFM technique. The main directions are:

* TiO2 anatase and rutile - these are well-understood oxides and serve as a substrate for testing the capabilities and limitations of the q-Plus technique.

* Cubic perovskites KTaO3 (001) and SrTiO3 (001) - The surface science of ternary oxides is relatively poorly understood compared to binary oxides. We have developed a procedure for preparing nice (1×1) bulk-terminated surfaces of these materials. Such surfaces offer an interesting playground for investigating the material stability, surface chemistry, electronic structure, incipient ferroelectricity, etc.

* Scintillating materials (Eu-doped alkali halides) - scintillation of these materials is closely related to defect chemistry of the Europium scintillation centers. nc-AFM allows for understanding the structure and properties of these defects.

* besides these topics, I closely collaborate with other group members on many binary oxides (In2O3, Fe3O4, Fe2O3, Ca2Ru3O7, etc.)
