Journal ArticleDOI
Ferromagnetism above room temperature in bulk and transparent thin films of Mn-doped ZnO
Parmanand Sharma,Parmanand Sharma,Amita Gupta,K. V. Rao,Frank J. Owens,Renu Sharma,Rajeev Ahuja,J. M. Osorio Guillen,Börje Johansson,Börje Johansson,G. A. Gehring +10 more
TL;DR: The first observations of ferromagnetism above room temperature for dilute (<4 at%) Mn-doped ZnO semiconductors are reported, promising new spintronic devices as well as magneto-optic components.
Journal ArticleDOI
Ledge-flow-controlled catalyst interface dynamics during Si nanowire growth
Stephan Hofmann,Renu Sharma,C. T. Wirth,Felipe Cervantes-Sodi,Caterina Ducati,Takeshi Kasama,Rafal E. Dunin-Borkowski,Jeffery Drucker,Peter Bennett,John Robertson +9 more
TL;DR: A video-rate environmental transmission electron microscopy study of Si nanowire formation from Pd silicide crystals under disilane exposure establishes an atomistic framework for nanowires assembly from solid catalysts, relevant also to their contact formation.
Journal ArticleDOI
In situ environmental TEM studies of dynamic changes in cerium-based oxides nanoparticles during redox processes
TL;DR: In the ceria-zirconia system, this work is able to use ETEM to follow the redox activity of individual nanoparticles and correlate this property with structure and composition, and finds considerable variation in theredox activity and interpret this in terms of structural differences between the nanoparticles.
Journal ArticleDOI
Oxygen vacancy migration in ceria and Pr-doped ceria: A DFT+U study
TL;DR: The presence of Pr significantly affects vacancy formation and migration, in a complex manner requiring the investigation of many different migration events, and a relationship illuminating the role of additional dopants toward lowering the activation energy for vacancy migration in PDC is proposed.
Journal ArticleDOI
In situ observations of carbon nanotube formation using environmental transmission electron microscopy
Renu Sharma,Zafar Iqbal +1 more
TL;DR: In this article, the in situ observations of the growth process of carbon nanotubes were reported, and a cubic phase was also observed to form on the walls of the multi-wall carbon nano-tubes.
