Large-scale defects hidden inside a topological insulator grown onto a 2D substrate
Danielle Reifsnyder Hickey, Ryan J. Wu, Joon Sue Lee +7
Topological insulator (TI) materials are exciting candidates for integration into next-generation memory and logic devices because of their potential for efficient, low-energy-cons…
Sub-Atomic Channeling and Vortex Beams in SrTiO
Jong Seok Jeong, Hosup Song, Jacob T. Held +1
Inspired by recent experimental sub-atomic measurements using analytical aberration-corrected scanning transmission electron microscopes (STEMs), we studied electron probe propagat…
An Inside Look at the Ti-MoS2 Contact in Ultra-thin Field Effect Transistor with Atomic Resolution
Ryan J. Wu, Sagar Udyavara, Rui Ma +5
Two-dimensional molybdenum disulfide (MoS2) is an excellent channel material for ultra-thin field effect transistors. However, high contact resistance across the metal-MoS2 interfa…
Decomposition of La2-xSrxCuO4 into Several La2O3 Phases at Elevated Temperatures in Ultra-High Vacuum inside a Transmission Electron Microscope
Jong Seok Jeong, Wangzhou Wu, Mehmet Topsakal +4
We report the decomposition of La2-xSrxCuO4 into La2O3 and Cu nanoparticles in ultra-high vacuum, observed by in-situ heating experiments in a transmission electron microscope (TEM…
