Momentum Matching for 2D-3D Heterogeneous Ohmic van der Waals Contact
Tara Jabegu, Ningxin Li, Aisha Okmi +5
Construction of ohmic contact is a long-standing challenge encountered by two-dimensional (2D) device fabrication and integration. van der Waals contacts, as a new solution for 2D…
A comprehensive correction of the Gaia DR3 XP spectra
Bowen Huang, Haibo Yuan, Maosheng Xiang +7
By combining spectra from the CALSPEC and NGSL, as well as spectroscopic data from the LAMOST Data Release 7 (DR7), we have analyzed and corrected the systematic errors of the Gaia…
Atomic-scale investigation of -GaO deposited on MgAlO and its relationship with -GaO
J. Tang, K. Jiang, C. Xu +4
Nominally phase-pure - was deposited on (100) within a narrow temperature window centered at 470 C using metal-organic chemical vapor deposi…
When the atoms dance: exploring mechanisms of electron-beam induced modifications of materials with machine-learning assisted high temporal resolution electron microscopy
Matthew G. Boebinger, Ayana Ghosh, Kevin M. Roccapriore +6
Directed atomic fabrication using an aberration-corrected scanning transmission electron microscope (STEM) opens new pathways for atomic engineering of functional materials. In thi…
On Distinctive Properties of Universal Perturbations
Sung Min Park, Kuo-An Wei, Kai Xiao +2
We identify properties of universal adversarial perturbations (UAPs) that distinguish them from standard adversarial perturbations. Specifically, we show that targeted UAPs generat…
