Transferring Orbital Angular Momentum to an Electron Beam Reveals Toroidal and Chiral Order
Kayla X. Nguyen, Yi Jiang, Michael C. Cao +13
Orbital angular momentum and torque transfer play central roles in a wide range of magnetic textures and devices including skyrmions and spin-torque electronics(1-4). Analogous top…
-phase Inclusions as Common Defects in Alloyed -(AlGa)O and Doped -GaO Films
Celesta S. Chang, Nicholas Tanen, Vladimir Protasenko +5
-GaO is a promising ultra-wide bandgap semiconductor whose properties can be further enhanced by alloying with Al. Here, using atomic-resolution scanning transmission el…
Adsorption-Controlled Growth of Ga2O3 by Suboxide Molecular-Beam Epitaxy
Patrick Vogt, Felix V. E. Hensling, Kathy Azizie +15
This paper introduces a growth method---suboxide molecular-beam epitaxy (S-MBE)---which enables the growth of Ga2O3 and related materials at growth rates exceeding 1 micrometer per…
An unexplored MBE growth mode reveals new properties of superconducting NbN
John Wright, Celesta Chang, Dacen Waters +8
Accessing unexplored conditions in crystal growth often reveals remarkable surprises and new regimes of physical behavior. In this work, performing molecular beam epitaxy of the te…
Crystal orientation dictated epitaxy of ultrawide bandgap 5.4-8.6 eV -(AlGa)O on m-plane sapphire
Riena Jinno, Celesta S. Chang, Takeyoshi Onuma +9
Ultra-wide bandgap semiconductors are ushering in the next generation of high power electronics. The correct crystal orientation can make or break successful epitaxy of such semico…
In situ modification of delafossite type PdCoO2 bulk single crystal for reversible hydrogen sorption and fast hydrogen evolution
Guowei Li, Seunghyun Khim, Celesta S. Chang +11
The observation of extraordinarily high conductivity in delafossite-type PdCoO2 is of great current interest, and there is some evidence that electrons behave like a fluid when flo…
Disentangling magnetic and grain contrast in polycrystalline FeGe thin films using four-dimensional Lorentz scanning transmission electron microscopy
Kayla X. Nguyen, Xiyue S. Zhang, Emrah Turgut +9
The study of nanoscale chiral magnetic order in polycrystalline materials with a strong Dzyaloshinkii-Moriya interaction (DMI) is interesting for the observation of magnetic phenom…
