Two-Dimensional Antimony Oxide

by Stefan Wolff, Roland Gillen, Mhamed Assebban, Gonzalo Abellán, and Janina Maultzsch

Author(s): Stefan Wolff, Roland Gillen, Mhamed Assebban, Gonzalo Abellán, and Janina Maultzsch

Two-dimensional (2D) antimony, so-called antimonene, can form antimonene oxide when exposed to air. We present different types of single- and few-layer antimony oxide structures, based on density functional theory (DFT) calculations. Depending on stoichiometry and bonding type, these novel 2D layers...

Flat and safe under the graphene sheet

by Claire Berger

Nature Materials, Published online: 27 March 2020; doi:10.1038/s41563-020-0666-z

Large-scale atomically thin metals can be stabilized through confinement epitaxy at graphene/SiC interface, which exhibit a gradient bonding type and are air stable, providing a compelling platform for quantum and optoelectronic technologies.

Anomalous Coulomb Drag between InAs Nanowire and Graphene Heterostructures

by Richa Mitra, Manas Ranjan Sahu, Kenji Watanabe, Takashi Taniguchi, Hadas Shtrikman, A. K. Sood, and Anindya Das

Author(s): Richa Mitra, Manas Ranjan Sahu, Kenji Watanabe, Takashi Taniguchi, Hadas Shtrikman, A. K. Sood, and Anindya Das

Correlated charge inhomogeneity breaks the electron-hole symmetry in two-dimensional (2D) bilayer heterostructures which is responsible for nonzero drag appearing at the charge neutrality point. Here we report Coulomb drag in novel drag systems consisting of a two-dimensional graphene and a one-dime...

by Jiaren Yuan, Yuanping Chen, Yuee Xie, Xiaoyu Zhang, Dewei Rao, Yandong Guo, Xiaohong Yan, Yuan Ping Feng, Yongqing Cai
Shrinking the size of a bulk metal into nanoscale leads to the discreteness of electronic energy levels, the so-called Kubo gap δ. Renormalization of the electronic properties with a tunable and size-dependent δ renders fascinating photon emission and electron tunneling. In contrast with usual three-dimensional (3D) metal clusters, here we...
