Masihhur R. Laskar,Digbijoy N. Nath,Lu Ma,Edwin W. Lee,Choong Hee Lee,Thomas F. Kent,Zihao Yang,Rohan Mishra,Manuel A. Roldan,Juan Carlos Idrobo,Sokrates T. Pantelides,Stephen J. Pennycook,Roberto C. Myers,Yiying Wu,Siddharth Rajan +14 more
TL;DR: In this paper, the first demonstration of substitutional p-type doping in large area few-layer films of (0001)-oriented chemical vapor deposited MoS2 was reported, where Niobium was found to act as an efficient acceptor up to relatively high density in MoS 2 films.
Journal ArticleDOI
Long-range ferromagnetic ordering in manganese-doped two-dimensional dichalcogenides
Rohan Mishra,Rohan Mishra,Wu Zhou,Stephen J. Pennycook,Sokrates T. Pantelides,Sokrates T. Pantelides,Juan Carlos Idrobo +6 more
TL;DR: In this article, the long-range ferromagnetism of Mn spins is mediated by an antiferromagnetic (AFM) exchange between the localized Mn $d$ states and the delocalized $p$ states of the S, Se, and Te atoms.
Journal ArticleDOI
Direct observation of ferroelectric field effect and vacancy-controlled screening at the BiFeO3/LaxSr1-xMnO3 interface.
Young-Min Kim,Anna N. Morozovska,Eugene A. Eliseev,Mark P. Oxley,Rohan Mishra,Sverre Magnus Selbach,Tor Grande,Sokrates T. Pantelides,Sergei V. Kalinin,Albina Y. Borisevich +9 more
TL;DR: An unexpected ~5% lattice expansion for regions with negative polarization charge is demonstrated, with a concurrent anomalous decrease of the Mn valence and change in oxygen K-edge intensity, which underline the non-trivial role of electrochemical phenomena in determining the functional properties of oxide interfaces.
Journal ArticleDOI
Evaluation of microstructure and mechanical property variations in AlxCoCrFeNi high entropy alloys produced by a high-throughput laser deposition method
TL;DR: In this paper, the crystal structure transitions from a disordered FCC to a mixture of disordered BCC and ordered B2 structures with increasing Al content, while the properties of the BCC/B2 structure were insensitive to composition.
Journal ArticleDOI
In Situ Observation of Oxygen Vacancy Dynamics and Ordering in the Epitaxial LaCoO3 System.
Jae Hyuck Jang,Young-Min Kim,Young-Min Kim,Qian He,Rohan Mishra,Liang Qiao,Michael D. Biegalski,Andrew R. Lupini,Sokrates T. Pantelides,Stephen J. Pennycook,Sergei V. Kalinin,Albina Y. Borisevich +11 more
TL;DR: A direct, real-time, atomic level observation of the formation of oxygen vacancies in the epitaxial LaCoO3 thin films and heterostructures under the influence of the electron beam utilizing scanning transmission electron microscopy (STEM).
