Manipulating the Structure and Properties ofColloidal Transparent Conducting Oxide Nanocrystals: From Spintronics to Solid State Lighting

Transparent conducting oxides (TCOs) have attractive physical properties, including structural versatility, transparency and ntype conductivity. The combination of transparency and conductivity is associated with the presence oxygen vacancies, which form shallow donor states. Imparting new functionalities into these complex materials through controlled introduction of native defects and dopants is therefore of significant fundamental and technological importance. While the electronic structure and properties of defects in TCO single crystals and thin films have been a dynamic area of research in the past decades, comparatively much less is known about their behavior in  nanostructures. In this talk I will review our recent efforts in introducing and controlling native and external defects in colloidal TCO NCs (particularly Ga2O3 and In2O3). I will describe the correlation between the NC growth, composition, metastability and defect structure, and the pathways for controlling magnetic and optical properties through defect interactions in these materials. This research was also expanded to other systems, such as IIIV semiconductor nanowires. The implications of our results for spintronic and photonic devices, such as light emitting diodes, will also be discussed.
