Tunneling current-controlled spin states in few-layer van der Waals magnets
ZhuangEn Fu, Piumi I. Samarawickrama, John Ackerman +12
Effective control of magnetic phases in two-dimensional magnets would constitute crucial progress in spintronics, holding great potential for future computing technologies. Here, w…
Small Energy Gap Revealed in CrBr3 by Scanning Tunneling Spectroscopy
Dinesh Baral, Zhuangen Fu, Andrei S. Zadorozhnyi +8
CrBr is a layered van der Waals material with magnetic ordering down to the 2D limit. For decades, based on optical measurements, it is believed that the energy gap of CrBr$_…
Designing Anisotropic Microstructures with Spectral Density Function
Akshay Iyer, Rabindra Dulal, Yichi Zhang +4
Materials' microstructure strongly influences its performance and is thus a critical aspect in design of functional materials. Previous efforts on microstructure mediated design mo…
Elongated Nano Domains and Molecular Intermixing induced Doping in Organic Photovoltaic Active Layers with Electric Field Treatment
Rabindra Dulal, Akshay Iyer, Umar Farooq Ghumman +5
The effects of the electric-field-assisted annealing on the bulk heterojunction nano-morphology in the P3HT/PCBM active layer of the organic photovoltaic cells (OPVCs) are presente…
Correlation between surface rumpling and structural phase transformation of SrTiO3
S. Singh, Te-Yu Chien, J. R. Guest +1
We present x-ray reflectivity, x-ray diffraction and atomic force microscopy measurements of single crystal SrTiO3 taken as a function of temperature. We found a rumpling transform…
Visualizing nanoscale electronic band alignment at the LaCaMnO/Nb:SrTiO interface
TeYu Chien, Jian Liu, Jacques Chakhalian +2
Cross-sectional scanning tunnelling microscopy and spectroscopy (XSTM/S) were used to map out the band alignment across the complex oxide interface of LaCaMnO…
A survey of fractured SrTiO surfaces: from the micro-meter to nano-meter scale
TeYu Chien, Nathan P. Guisinger, John W. Freeland
Cross-sectional scanning tunneling microscopy was utilized to study fractured perovskie oxide surfaces. It was found for the non-cleavable perovskite oxide, SrTiO, that atomi…
Nanometer-scale striped surface terminations on fractured SrTiO surfaces
Nathan P. Guisinger, Tiffany S. Santos, Jeffrey R. Guest +4
Using cross-sectional scanning tunneling microscopy on in situ fractured SrTiO, one of the most commonly used substrates for the growth of complex oxide thin films and superl…
Surface Geometric and Electronic Structure of BaFe2As2(001)
V. B. Nascimento, Ang Li, Dilushan R. Jayasundara +15
BaFe2As2 exhibits properties characteristic of the parent compounds of the newly discovered iron (Fe)-based high-TC superconductors. By combining the real space imaging of scanning…
