Imaging the Flow of Holes from a Collimating Contact in Graphene

Sagar Bhandari, Mary Kreidel, Alexander Kelser +5

A beam of holes formed in graphene by a collimating contact is imaged using a liquid-He cooled scanning probe microscope (SPM). The mean free path of holes is greater than the devi…

Evidence of Higher Order Topology in Multilayer WTe from Josephson Coupling through Anisotropic Hinge States

Yong-Bin Choi, Yingming Xie, Chui-Zhen Chen +12

The noncentrosymmetric Td-WTe, previously known as a type-II Weyl semimetal, is expected to have higher order topological phases with topologically protected, helical one-dimen…

Graphene-based Josephson junction microwave bolometer

Gil-Ho Lee, Dmitri K. Efetov, Woochan Jung +8

Sensitive microwave detectors are critical instruments in radioastronomy, dark matter axion searches, and superconducting quantum information science. The conventional strategy tow…

Spin-phonon interaction increased by compressive strain in antiferromagnetic MnO thin films

Alireza Kashir, Veronica Goian, Oliva Pacherova +3

MnO thin films with various thicknesses and strains were grown on MgO substrates by pulsed laser deposition, then characterized using x-ray diffraction and infrared reflectance spe…

Strain-induced increase of dielectric constant in EuO thin film

Alireza Kashir, Hyeon-Woo Jeong, Woochan Jung +2

Recently, lattice dynamics of the highly strained europium monoxide, as a promising candidate for strong ferroelectric-ferromagnet material, applied in the next-generation storage…

Dielectric properties of strained NiO thin films

Alireza Kashir, Hyeon-Woo Jeong, Gil-ho Lee +2

The dielectric properties of NiO thin films grown by pulsed laser deposition have been studied as a function of strain at temperature from 10 to 300 K. Above 150 K, the contributio…

Pulsed Laser Deposition of Rocksalt Magnetic Binary Oxides

Alireza Kashir, Hyeon-Woo Jeong, Gil-ho Lee +2

Here we systematically explore the use of pulsed laser deposition technique (PLD) to grow three basic oxides that have rocksalt structure but different chemical stability in the am…
