Interferometric 4D-STEM for Lattice Distortion and Interlayer Spacing Measurements in Bilayer and Trilayer Two-dimensional Materials

Michael J Zachman, Jacob Madsen, Xiang Zhang +3

Van der Waals materials composed of stacks of individual atomic layers have attracted considerable attention due to their exotic electronic properties that can be altered by, for e…

Nanoscale probing of image-potential states and electron transfer doping in borophene polymorphs

Xiaolong Liu, Luqing Wang, Boris I. Yakobson +1

Using field-emission resonance spectroscopy with an ultrahigh vacuum scanning tunneling microscope, we reveal Stark-shifted image-potential states of the v_1/6 and v_1/5 borophene…

Apparent Ferromagnetism in Exfoliated Ultra-thin Pyrite Sheets

Anand B. Puthirath, Aravind Puthirath Balan, Eliezer F. Oliveira +11

Experimental evidence for ferromagnetic ordering in isotropic atomically thin two-dimensional crystals has been missing until a bilayer Cr2Ge2Te6, and a three-atom thick monolayer…

Large optical tunability from charge density waves in 1T-TaS under incoherent illumination

Weijian Li, Gururaj V. Naik

Strongly correlated materials possess a complex energy landscape and host many interesting physical phenomena, including charge density waves (CDWs). CDWs have been observed and ex…

Stress-Induced Intercalation Instability

Youtian Zhang, Ming Tang

We present a linear stability analysis to demonstrate that a flat coherent phase boundary formed by the (de)intercalation of solutes into a compound is unstable against perturbatio…

Terahertz Excitonics in Carbon Nanotubes: Exciton Autoionization and Multiplication

Filchito Renee G. Bagsican, Michael Wais, Natsumi Komatsu +10

Excitons play major roles in optical processes in modern semiconductors, such as single-wall carbon nanotubes (SWCNTs), transition metal dichalcogenides, and 2D perovskite quantum…

Correlating Structural, Electronic, and Magnetic Properties of Epitaxial VSe2 Thin Films

Guannan Chen, Sean T. Howard, Aniceto B. Maghirang +9

The electronic and magnetic properties of transition metal dichalcogenides are known to be extremely sensitive to their structure. In this paper we study the effect of structure on…
