Dynamics of Polar Skyrmion Bubbles under Electric Fields
Ruixue Zhu, Zhexin Jiang, Xinxin Zhang +18
Room-temperature polar skyrmion bubbles that are recently found in oxide superlattice, have received enormous interests for their potential applications in nanoelectronics due to t…
Lattice dynamics, phonon chirality and spin-phonon coupling in 2D itinerant ferromagnet Fe3GeTe2
Luojun Du, Jian Tang, Yanchong Zhao +13
Fe3GeTe2 has emerged as one of the most fascinating van der Waals crystals due to its two-dimensional (2D) itinerant ferromagnetism, topological nodal lines and Kondo lattice behav…
Gate-dependent Pseudospin Mixing in Graphene/Boron Nitride Moire Superlattices
Zhiwen Shi, Chenhao Jin, Wei Yang +13
Electrons in graphene are described by relativistic Dirac-Weyl spinors with a two-component pseudospin1-12. The unique pseudospin structure of Dirac electrons leads to emerging phe…
Systematic Determination of Absolute Absorption Cross-section of Individual Carbon Nanotubes
Kaihui Liu, Xiaoping Hong, Sangkook Choi +9
Determination of optical absorption cross-section is always among the central importance of understanding a material. However its realization on individual nanostructures, such as…
In situ TEM investigation of oxygen migration as a key mechanism for resistive switching in Pr0.7Ca0.3MnO3
Zhaoliang Liao, Peng Gao, Xuedong Bai +1
Low temperature growth Pr0.7Ca0.3MnO3 (PCMO) thin film showed high performance in electric field induced resistance switching (RS). To understand the micro-mechanism of RS in Metal…
