Self-assembled nanocomposites with a high interface-to-volume ratio offer an opportunity to overcome limitations in current technology, where intriguing transport behaviors can be tailored by the choice of proper interactions constituents. Here we integrated metallic perovskite oxide SrRuO3-wurzite semiconductor ZnO investigate room-temperature metal-insulator transition and its effect on photoresponse. We demonstrate that band structure at interface tuned controlling nanocomposites....
Nanocrystals (NCs) attract tremendous research interests because of their unique properties to meet the demands functionalities. To date, hybrid NCs with multiple components are developed rising that could be very difficult, or even impossible achieved by single-component NCs. Tuning strain via conjugation an alternative solution. Strain engineering has been discovered and widely applied many thin-film materials for tuning physical properties. Then, there is a further question addressed in...
Complex oxide nanocrystals with a spinel structure show their remarkable optical, electronic, mechanical, thermal, and magnetic properties. In this study, we present simple yet versatile strategy to grow self-assembled epitaxial CoFe2O4 well-controlled size (less than 10 nm) single orientation. were fabricated via phase separation in BiFeO3-CoF2O4 ultrathin film by pulsed laser deposition. The coherent strain at the interface suppressed growth of regardless substrate temperatures. This also...
We investigate the anisotropic stress dependent magnetic and phonon behaviors in self-assembled CoFe2O4-PbTiO3 (CFO-PTO) nanostructures deposited on SrRuO3 buffered SrTiO3 substrates of various thickness. The increased vertical compressed with increasing thickness enhances anisotropy CFO while gradually reducing polarization PTO. By applying magnetic-field Raman scattering, CFO-A1g T2g(1) frequencies shift oppositely because magnetostriction. Moreover, PTO-A1 mode intensities anomalously...
