Journal ArticleDOI
Nanoscale Piezoelectric Properties of Self-Assembled Fmoc-FF Peptide Fibrous Networks.
Kate Ryan,Jason Beirne,Gareth Redmond,Jason I. Kilpatrick,Jill Guyonnet,Nicolae-Viorel Buchete,Andrei L. Kholkin,Brian J. Rodriguez +7 more
TL;DR: Structural analyses of Fmoc-FF nanofibrils suggest that the observed piezoelectric response may result from the noncentrosymmetric nature of an underlying β-sheet topology.
Journal ArticleDOI
AlN bulk crystals grown on SiC seeds
TL;DR: In this paper, a two-step deposition process was developed for the growth of thick AlN layers with thickness between 0.1 and 3 mm and cracks formed due to the thermal expansion mismatch between AlN and SiC were observed to decrease with increase in AlN thickness.
Journal ArticleDOI
Local bias-induced phase transitions
Sergei V. Kalinin,Brian J. Rodriguez,Stephen Jesse,Peter Maksymovych,Katyayani Seal,Maxim Nikiforov,Arthur P. Baddorf,Andrei L. Kholkin,Roger Proksch +8 more
TL;DR: In this article, the authors review methods for probing bias-induced phase transitions and discuss the current limitations and challenges for extending the methods to field induced phase transition and electrochemical reactions in energy storage, biological and molecular systems.
Journal ArticleDOI
Dual harmonic Kelvin probe force microscopy at the graphene-liquid interface
Liam Collins,Jason I. Kilpatrick,Ivan Vlassiouk,Alexander Tselev,Stefan A. L. Weber,Stephen Jesse,Sergei V. Kalinin,Brian J. Rodriguez +7 more
TL;DR: In this article, dual harmonic (DH)-KPFM was used to probe electrochemistry at the solid-liquid interface of graphene-based electrochemical capacitors, and the results showed good agreement with measurements performed in air.
Journal ArticleDOI
Spatially resolved mapping of ferroelectric switching behavior in self-assembled multiferroic nanostructures: Strain, size, and interface effects
Brian J. Rodriguez,Stephen Jesse,Arthur P. Baddorf,T. Zhao,Ying-Hao Chu,Ramamoorthy Ramesh,Eugene A. Eliseev,Anna N. Morozovska,Sergei V. Kalinin +8 more
TL;DR: In this paper, local ferroelectric polarization switching in multiferroic BiFeO3-CoFe2O4 nanostructures was studied using switching spectroscopy piezoresponse force microscopy (SS-PFM).
