Patterning of Fine Features on Material Surfaces Using a Ga Ion-Beam in a FIB-SEM
Supriya Ghosh, K. Andre Mkhoyan
Since an ion-beam is a viable attractive alternative to other material surface patterning techniques like an electron-beam, a study of the structure, composition and dimension of p…
Mending Cracks in Rutile TiO with Electron Beam
Silu Guo, Hwanhui Yun, Sreejith Nair +2
Restructuring of rutile TiO under electron beam irradiation driven by radiolysis was observed and analyzed using a combination of atomic-resolution imaging and electron energ…
Strain effect on the ground-state structure of Sr2SnO4 Ruddlesden-Popper oxides
Hwanhui Yun, Dominique Gautreau, K. Andre Mkhoyan +1
Ruddlesden-Popper (RP) oxides (ABO) comprised of perovskite (ABO) slabs can host a wider variety of structural distortions than their perovskite counte…
Co-operative Influence of O2 and H2O in the Degradation of Layered Black Arsenic
Mayank Tanwar, Sagar Udyavara, Hwanhui Yun +3
Layered black arsenic (b-As) has recently emerged as a new anisotropic two-dimensional (2D) semiconducting material with applications in electronic devices. Understanding factors a…
Challenges to magnetic doping of thin films of the Dirac semimetal CdAs
Run Xiao, Jacob T Held, Jeffrey Rable +4
Magnetic doping of topological quantum materials provides an attractive route for studying the effects of time-reversal symmetry breaking. Thus motivated, we explore the introducti…
A New Line Defect in NdTiO3 Perovskite
Jong Seok Jeong, Mehmet Topsakal, Peng Xu +3
Perovskite oxides form an eclectic class of materials owing to their structural flexibility in accommodating cations of different sizes and valences. They host well known point and…
